Which cyl has the skip and which coil did you replace? There are 8 coils? right? Replace the spark plugs with Motorcraft Spark Pugs ONLY.

Changed sensor 1 bank 1 and found I have four on 96 Yukon makes noise like putting underneath. Now want start. Wuts wrong

tell me did, did skipping start after you replace oxygen sensor or did vechicle already have skip before sensor change if so skipping can be caused by intake leak,bad spark plugs and wires,could have restricted fuel filter, weak fuel pump or weak ignition coil. if skipping occur after you replaced oxygen sensor could have loose sensor or cross thread sensor threads causing exhaust leak around oxygen sensor.

I have a 93 grand cherokee lerado with the 5.2 engine. the first thing to happen is the ignition coil went all of a sudden while driving. replaced the coil and ran great for two weeks then it started to...

How did you determine bad coil? was it not sparking period? I ask because coils rarely if ever go bad... What is the fuel pressure? Are the injectors firing? Spark plugs fouled?
Other sensors to check: Coolant temp sensor? Manifold air temp or intake air temp sensor? O2...These will change your air/fuel mix at temp if they're bad...

Replaced some coils and still skipping. When I drive the truck skips and shakes alot what should I do about it.

Some coils? how did you know which ones? You need to replace allof the spark plugs and the coils that may be bad. its too expensive to guess, take it to a shop that can tell you which cylinders are misfiring. the coils may not be what the problem is.

What would be my problem when my jeep is skipping really bad, i changed the plugs already and had a engine check done on it, wold it be the coils? and how would i fine out which one?

It could be bad coils. That can be checked by running the vehicle with one of the spark plugs unplugged at a time. Shut it off before trying to remove the plug or you may get a nasty shock from any working coil. Good luck!

2003 Chevy Impala 3.8L #3 and #6 not firing, we replaced the coil still not firing. Husband doesn't think 2 plugs would go bad at the same time any suggestions?

may be a bad module it is under the coils I think 3 and 6 are on the same coil so that would make both cyls not fire

Skipping when gets warmed up

Is the check engine light on? If so get the code it will tell yoou which cylinder if it is a coil. These have 8 coils on them I think and each one can go bad. I just replaced all the coil packs on my moms Lincoln, Everytime I would replace one another would go bad, it had 200,000 miles on the old ones. I ended up just replacing them all, because I didn't want her to get off somewhere and have problems.

If it's not thrown a code it is most probably a vacumn leak/bad plug/bad injecctor.
