Try the ignition module.This is more than likely your problem.It is on the coil pack where the wires connect to.I have had a few of these go on me.This should take care of your problem.Hope this helps.Good luck.

I have a '03 Toyota Celica GT-S with a annoying mis-fire. Started small by replacing all spark plugs - nothing. Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked...


Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

On a 1998 dodge stratus 2.4 ltr engine misfire


check compression,with engine running remove h/t leads 1 at a time to diagnose weak cylinder,check that cylinder has the same amount of spark ( jumps the same gap as others )try changing the plug from crook cylinder to a good one and note if miss follows that spark plug or stays with same cylinder,can do same with injectors but only perform one procedure at a time so you can determine which one works.

My 2001 chevy blazer is misfiring and will not rev beyond 2000rpm without cutting out but it idles alright


trying to rev the engine in neutral will not work. the computer will limit the rpms.it is kind of a goofy safety measure built into the system. to diagnos the missfire you can remove one plug wire at a time with an insulated pliers.the missfireing one will -not-slow down the engine speed. if all cylinder are firing properly at idle and only misfires under load you will probably need some help have a driver put on the brake and accelerate a little untill it misses. when you have verifyed this try the same thing with the plug wires while it is missing. do not keep the engine torqed this way for more thn a couple of seconds. you could damage the trans.. when you locate the missing cylinder you will need to find out why it is missing. look at the spark plug,and maybe swap one plug wire for another to see if the missfire moves to another cylinder. i am assuming you have no test equipment. if that does not change,see if you can get at that injector for that cylinder and lightly tap on it with a metal punch.if problem seems to go away or engine misses when tapping injector it will need to be replaced.
