Ok so my friend and I were driving my car and he already has owned an rx7 fpr a while and he said my car was running rough and it could have been misfireing. Would it just be the spark plugs and wires or what, I was wondering how could i fix the misfire or is it even missfire if my engine runs rough in the higher rpms, if you could help plz. Thx

 

Try adjusting TPS, the A/F...check timing too...vacum leaks...etc...



What RPM is it doing it at?

 

well if u saw an earlier thread i was complaining about hight idling(about 2000 somethimes 2500rpm) but it rides rough in the higher rpms, i havnt fixed my idling problem either.

 

Just outta curiosity, have you looked at your airfilter lately? Its not melted or anything, is it?

 

Haha funny, I just bought a highflow intake.

 

Ha! I was just askin' cause mine melted into my AFM and the AFM wouldnt move much at all...and my car did the same **** your talkin about (except the high idle)

 

S anyways besides that o you know what it could be?

 

Plz someone else help cause that didnt really help plz

 

If you had an idle problem I would focus on the throttle position sensor(s) (TPS)

 

ok cool so then i fix the tps by turning that screw right?
