my money would be on the coil cover, especially if it had been a long time since the last tune up. it is certainly worth trying, as this is part of a routine tune up anyways. good luck!

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.

99 dodge caravan #4 cylinder misfires, i replaced spark plug wires and spark plugs. Scanner showed #4 still misfiring, could this be the coil?


It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.

ok since you said you changed the plug and coil pack, start with the injector wire harness and look it over for any shorts or grounds, also make sure the terminals on the no.2 injector connector aren't loose. if you have access to a noid light you can check to make sure the injector is pulsing. check the no.2 plug wire as well. swap it with another wire if you can and see if the miss follows the plug wire. if those fail to solve your problem and the misfire remains on the no.2 cyl, try swapping an injector. if that also fails then you may have a problem with the cyl head.

Cylinder 5 missfire 1999 tahoe


How is the pressure in the fuel rail? a low pressure will cause erratic firing of the injectors - the further down the rail u get usually the worse the problem. If the fuel filter was not changed regularly or if the vehicle stood for a while, dirty fuel/standing fuel at some time in the recent past, this **** will accumulate in tyhe injectors. To avoid spending a loada cash, swap a few injectors around and see if the problem moves with the injector.
