Experienced mechanics share their insights in answering this question :
Hello…If the check engine light is flashing, that signifies a condition, such as active engine misfiring, that should be investigated and resolved promptly to avoid further damage to engine components, not to mention the catalytic converter. The recommended service is a check engine light diagnostic. The responding certified mechanic will download the diagnostic trouble codes that have caused the check engine light to illuminate and then begin the diagnosis from there using those codes. The possibilities range from ignition system faults such as defective spark plugs or coils to fuel system problems such as inadequate fuel pressure, defective (plugged) fuel injectors, and air induction system problems. Whatever the issue is, the fact that codes have set, and are downloadable, means that the root cause will be fairly readily identified by the mechanic. Once identified, the mechanic will be in a position to give you a cost estimate for the required repairs. If you have further concerns, by all means let us know.

Check engine light flashing then stops when accelerating is a sign of a cylinder misfiring due to a fuel delivery system issue such as a bad fuel injector, dirty fuel pump, and a clogged fuel filter or fuel line.
The most likely problem is an engine misfiring from an ignition problem, such as a failed spark plug, plug wire, or coil problem. Some of these engines may also have problems with fuel injectors. I recommend having the Check Engine Light diagnosed by a certified mechanic, such as one from YourMechanic.
Flashing engine light and car shaking during acceleration indicate a misfire. As we said earlier, misfires arise from various issues including bad spark plugs, faulty ignition coils, bad fuel injector, blocked fuel filter, faulty idle air control valve, and so on.
The Check Engine Light going on and off is most likely caused by an engine misfire. The intake manifold could be leaking vacuum when it is cold, and sealing up when the vehicle warms up. The engine running poorly can prevent the engine from getting up to operating temperature as fast as it should.
If you have faulty spark plugs, the fuel can`t ignite properly and the cylinders will misfire. This misfiring can cause your car to jerk when accelerating, while maintaining speed as well as vibrate excessively when idling.
There are a few reasons your car may shake when accelerating but not coasting. The most common reason is that the engine is misfiring. When the engine misfires, it doesn`t run as smoothly as it should and can cause the car to shake. Another possible reason is that the spark plugs or ignition coils are dirty or damaged.
Potential causes of a vehicle shaking at idle include a loose gas cap, loose battery cables, a worn throttle sensor, a damaged engine mount, or bad spark plugs. Perform a general inspection of your engine bay to look for damage. If you can`t repair the problem yourself, take the vehicle to a mechanic.
Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean.
There is no set time limit, as the severity of the problem can vary. However, it is generally not advisable to drive for more than a few miles with a flashing check engine light. If possible, have the vehicle towed to a repair facility rather than driving it so that you do not put yourself or others at risk.

I have white milk coming out of my exhaust pipe but I don’t see it mixing in my oil pan when I check my oil
ANSWER : In most cases, the white smoke is an indicator of coolant finding a way into the combustion chamber. This could happen through a damaged head gasket or a crack in the cylinder head or engine block. Most of the time, this would also be followed by milky oil or overheating problems. However, it could also be a problem with the EGR system, or an extremely rich fuel trim. The best thing to do is have a professional mobile mechanic complete a smoke coming from exhaust inspection, so they can pinpoint the source of your issues and recommend a repair.

Check Engine Light comes on after starting pickup
ANSWER : Hello there, thank you for asking about your 1992 Isuzu Pickup. A professional will have the correct equipment to read OBD1 codes. Retrieving the diagnostic trouble code(s) is the first place to start when diagnosing your vehicle. Increasing RPMs changes engine load, which can in turn affect many different sensors and components, causing the Check Engine Light to illuminate. The only way to narrow down the options and find the culprit is through in person diagnosis with an OEM compatible scan tool. A certified technician from YourMechanic can retrieve the OBD codes at your home or office.

Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.

Car goes into limp mode when the check engine light and VSA light comes on
ANSWER : The lights that you have on and the vehicle going into fail safe mode is an indication you have a major system failure that will require computer to be tested for codes first. There are many possible codes it can be so the additional testing will be needed to isolate the cause of the problem.

I am not getting any power when I turn the key to the on position. there is no dash lights only check engine lite comes on.
ANSWER : The problem of having erratic electrical issues with this year Bronco they have problems with the ignition switch losing contact. You should check and replace the ignition switch. When the switch is removed you should check linkage rod and electrical connector for problems and repair as needed along with replace the ignition switch.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.

I have gray smoke coming out of my tailpipe but it’s not heavy smoke and my car check engine light is orange​ my car shut off
ANSWER : You did not mention why the radiator was replaced but I think your engine was overheated causing the head gasket to go bad. This would cause the white smoke out of the tail pipe and an engine misfire and overheating can cause the check engine light to be on. I recommend having the engine checked for leaking head gasket and scan the computer for codes.
