The modules are sensitive to heat so they can cause the engine to shut off, then, after cooling down, the car will start and run like nothing happened.As it gets worse,it will happen more often until the car fails to start.
Remove it and test it. A good service manual for your car should tell you what to look for. If you don't have an ohm meter to test it, remove the coil and take it to a reputable auto parts retailer in your area.
You can do it yourself by going to troubleshootmyvehicle.com(the author is correct) or take it to oreilly auto parts or autozone. They both will test it for you...Take it to both places..a second opinion never hurts...good luck....
depends on type of vehicle. on a c.o.p. system(coil on plug)...the check eng. lite usually will come on to tell u which cylinder it is or random misfire. code 301 is cyl. #1 and 302 is cyl#2 on so on. random misfire is hard to pin point, i use a scanner. pep boys and like only read codes and not data stream(live activity)so unless you want to replace all coils then need to bite the bullet and take it to us(cert. automotive tech.)
It is important to recognize the signs of car parts going bad. The symptoms of an ignition coil going bad are bad fuel economy, backfiring, starting problems and engine misfiring.
bad fuse,bad coils, bad ignition modual
You will have to have it scanned for codes, check with your parts house. They may scan for you.
depends on early or late model. lots of early models will just shut off while driving down the road etc, and never start again. cant rmember right now on late ,mind is on another project, sorry
Check the ignition coils and the crank sensor for the Yukon. Either one of these could be bad and cause the problem.
The ignition tumblers are part of the cylinder , they are internal and are what differentiate the key cuts. They do occasionally stick and bind the ignition cylinder
a '95 riviera does not have a distributor. If you mean the ignition coils, then you probably looking at bad ignition module-located under the coils. Or bad crank sensor.
bad fuse,bad coils, bad ignition modual
Ignition coils can go bad with age. They can also be damaged by a bad alternator putting out improper or unclean voltages.
Less performance, economy, harder to start cold.
No
Unplug ignition coils one at a time until you find the one that doesn't effect the rpm's.That's the one that's bad.
It is important to know the symptoms of a part going bad. The signs of an ignition switch going bad is it overheating, no clicking when trying to start, the car has issues starting and running.
Bad coils or perhaps a bad crankshaft position sensor.
A bad coil can damage a converter. If the engine is misfiring, it will cause raw fuel to get into the converter and that can cause failure.
Ignition coils are very rugged and reliable, but can fail for a variety of reasons. Heat and vibration can damage the coil's windings and insulation causing shorts or opens in the primary or secondary windings. But the number one killer of ignition coils is voltage overload caused by bad spark plugs or plug wires. So the answer to your question is yes. Do regular tune ups
IF IT IS A 4 CYL YOU PROBABLY HAVE A BAD CRANK SENSOR OR IGNITION MODULE.
You will have to have it scanned for codes, check with your parts house. They may scan for you.
