after install wirings and kit, i started the car but then it's miss firing from cylinder #2..
we swap the injector and coil...
after swap it was fine for awhile..
but then after 1hr, its miss firing again...
wtf is going wrong?

 

How are you diagnosing the misfire? Is this at idle? Or just cruising around?

Are you getting a CEL?

 

i just fixed problem.....it was miss firing at the idle....so we just swap coils and its fine now......
thank god.....

 

i got the same prob now.... gave a cel did a clear and it gave a mis in 3 and 5...but today after running a srt4 and beatting him the light went off...greddy states that it could be the weather since im running a 8 instead of a 7...or lines ...i checked lines ands they looked ok..they said to go w/7's and then during summer run 8's...im going with a buddy check the gaps...that could also cause the code.but then again there supposed to be pregaped... but ill let ya know how it turns out

 

Check your lower injector o-rings are not pinched.

 

thanks ill do that aswell
