my car feels like its misssing big time. I need some tips where to start my search. im gonna check that all plugs are getting spark, make sure no wires are messed up at all and cross-sparking or grounding somewhere else. a big thing also could be an injector? i think the fuel psi may have gone too high in the last few days (60ish) and these injectors are stock.

any other tips ?

 

i wouldn't bother checking for spark and all that, i'd just replace all the tune up related parts, unless you just did that last week.

 

ive always kept my car up to tune.

i might add in, most of the time when i start it fresh, (cold engine) it wont do it for a few minutes.

 

Check your injector resistance if you have all the tune-up stuff done to it. A bad injector will cause a miss as well.

 

how can i check the resistance?

 

with one of these guys

$10-20

 

i have one of those but its analog. but im really ****ty with them, do i just unplug the wire from the injector, plug that multimeter in and see what it reads? what setting do i set it to, and what should the readings be.
