Ok, so my car acts like it is misfiring but it only does it when i am driving. Like on the interstate it hesitates.....Anyone know why?


Could it be my injectors?

 

It does it all the time usually.....Mainly while i am just cruising at 45 or on the interstate doing around 80.

 

Tough to diag on the net but a part throttle cruising miss in my experiences has been,plug wires,cracked porcelin on a plug,turbulence around the MAF will create a part throttle stumble,lazy O2's,etc...


Hope that helps

 

Thanks guys...

So i should just have the codes pulled first then go from there?

 

Plugs and wires from my experiences won't throw trouble codes on your car.

 

any changes to the car around the time it started?

 

Uh not really. I mean my car sometimes just stalls. It will be ideling and it jumps from 1000rpm to 500rpm and then just stalls but someone said it is from my broken catalytic converter. So I am gettin the hpipe but i wanted to try and get that fixed too.

 

id just get new coils, plugs and wires if you havent done it recently....
