Misfiring and Running Rich
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 35-00 - -
16687 - Cylinder 3: Misfire Detected
P0303 - 35-00 - -
16686 - Cylinder 2: Misfire Detected
P0302 - 35-00 - -
17535 - Fuel Trim; Bank 1 (Mult): System too Rich
P1127 - 35-00 - -
'01 A4 1.8TQM w/ PES T28 kit..those are the codes im throwing right now...i swapped coil packs to see if they were bad, but theyre fine...so im guessing its the spark plugs...will be ordering some soon....but i only misfire when wot past 5k rpms..
1) Im wondering if the car running rich would cause me to misfire?
2) i did a log on block 032 and the at idle additive is -1.5% which seems fine but the P. throttle mult is -25% which is out of the -10 - 10% its supposed to be between...need some guidance there
3) Everything is passed on my readiness test except for secondary air system and oxygen sensors...
4) Im running 440 cc rc engineering injectors which flow at 43 psi...but i think my fpr is still the stock 4 bar - 54 psi fuel pressure regulator....is this why im running rich?

RE: Misfiring and Running Rich
OR you didn't start the engine as you thought then the EVAP system would throw a fault to prevent damage to the cat, so im guessing you had a problem starting the engine?? flooded let it dry out then try again

difficult to answer without codes but the secondary pump should shot off in 2 secs, EVAP clicks as does the fuel pump relay and if this happens thefault is engine/electrics related so perhaps you could explain the problem with more detail

i did the pressure test...all i heard was a bubbling sound from some liquid somewhere towards the driver side on bottom...view from standing in front of the engine looking in. any ideas??

RE: Misfiring and Running Rich
changed plugs...runs a little better now and my coil packs dont pop up anymore...i knew since i was running rich, my plugs would be black, except when i pulled my 3rd cylinder plug out it was clean on the end...was i not getting enough fuel to that cylinder?
