Hey guys/gals
My car has started missing at idle out of nowhere and i cant quite figure out why
I know most lines have a very slight miss when idling and mine did too
But now its constant like every 2 seconds, not quite as bad as having dropped a cylinder though.
-It misses more as the oil temps go up
-If i step on the gas in neutral and hold the revs eg: 2000rpm it still misses a bit but not as bad as when its idling
-It used to misfire a bit on boost (16psi) with the old coils but with the new ones it doesn't at all.
-I'm not down on power at all and the car drives normally.
Ive just put in a set of new justjap coilpacks, new spark plugs and gave the afm and aac valve a good clean
The coils helped a bit but it still misses
Raised the idle a tad and that didn't help
Ran some injector cleaner but i might try another brand as well
Checked all the cooler piping for leaks and my vaccum pressure hasn't changed
Fuel filter has been changed
I'm going to try a different ignitor pack and see if that makes a difference
I've considered a bad injector, how can i tell if one of my injectors are blocked/leaking?
What would i be looking for if i put it on a dyno?
Would the TPS have anything to do with this?
Im running an RB20 with:
RB25 highflow
GTR injectors
Z32 afm
040 fuel pump
Ecu remap
What else could it be?
