Check the EGR valve. Look up on the internet where on your car it is located. Find the vacuum line connected to it. Start the engine cold and as it warms up and starts to miss and stumble, pull off the vacuum line from the EGR. If the car idles fine, replace the EGR. Ignition system problems are more likely to occur at idle or lower rpm. Besides, testing the EGR is free, easy and do fail in high mileage vehicles.

Ihave a 1996 f150 reg cab with dual fuel tanks. This has the 4.9 6 cyl. Truck runs great until it hits normal operating temperature, then it will miss and buck for a short time then starts running nor

I think you need to check a lot of things here because all are related 1st disconnect the battery cables and do not use a brush it ripps the battery post to shreds use 4/0 that's 0000 steel wool and pb blaster or liquid wrench and clean all connections from the battery the power disribution box the starter and the engine grounds once that is done reconnect your battery cables and just turn the key to the run position but do not crank the engine and observe the dash lights your computer is in self test mode and all warning lights for check engine abs airbag should go out if any stay on there's a code set and it must be read if not next start the engine and let it warm to normal temperature and go driving to see if it happens again if not good if it does then we must go deeper remove spark plugs and check for a antifreeze leak and all boots for cracks and spark plug gap if there's a leak or a bad plug boot it will let the +spark escape to- ground causing a misfire also a bad coil if cracked will let spark escape after it gets hot enough from continuing to operate to wind cooled then it will contract and close the air gap slightly next bad vacuum lines and next sometimes there's a dead spot in you throttle position sensor from normal wear and when you get to that spot missing will occur as well as the idle air control valve will do the same this is a heat expansion issue that's why so many different possible causes write everything down that you did so if it is still happening we can rule out things and continue to find the cause ok good luck stephen

2002 Ford Escape, the engine was cleaned and now showing a misfire on cyclinders 1,4&5? Swapped a coil and it made no difference? Run good when cold but starts missing when warmed up?

You don't clean todays engines,not with water anyway

I would say seeing as how you have been walking
coils,which is all you can do,without the proper
test equipment

You have 1 bad coil

You need to buy 1 new one and put it in a cyl
Drive at least 25 miles
If it still misses,put back the original one and
move the new one one cyl

They only misfire when really hot and will
set all kinds of codes
So on a Ford Product you disregard the codes
and keep switching the NEW Coil

Hi, I have a 1998 2door accent 130i. Starting fine as usual. as warm up progresses I have what sounds like ignition missfireing until temp meter just starts to show temp increase. Then no more missing and...

yes you hit the nail right on the head there,, its the tem sensor playing you up, its telling the car's computer its warm when its still cold and it cuts back the fule like pushing in the choke,,, this causes the engine to miss fire and lack power till its warm change the sensor

'97 A4 1.8T, coolant leak resulted in brief overheat,leak fixed,diag.code now shows #2 cyl.missing (badly), compression good,injectors good,coils/plugs good,missing badly,could the brief overheat have

did the car over heat for long?
there could possibly be damage to your head like warping due to overheating and blowing a head gasket or something along those lines .
first check the oil dipstick is it milky?
then check the coolant is it oily?
and when it is running is it blowing any white smoke?
if you replaced the plugs and it is misfiring did you plug the wire all the way back on the plugs if not then the problem is a plug wire being loose and loosing connection with the plug.
sounds like a simple fix if you don't have water in your oil or white smoke coming out the exhaust.
troubleshooting it can be a bigger job but if you nail the right symptoms down you can corner the problem.
like if it is a coil pack or bad wire switch them with another one and see if the problem follows the wire or coil pack.for instance take the number one plug wire off and the number two wire off and put the number one wire on number two and see if the number one misfires. if so then the wire is the problem if not then try numbers three and four until you find out which cylinder is the culprit.
good luck and happy hunting.
