z32 maf
stock injectors
Ok it started a few days ago when i hit a road bump. Car started to run sluggish, and misfired from the 1st cylinder. I thought maybe the coil packs and harness went bad so i changed those and the spark plugs which were done pretty much. Changed them issue still kept going new spark plugs were blackened and bad. thought maybe fuel pump went bad but that wasn't the problem causethe car still got fuel and ran rich. Yesterday decided to check the maf and disconnected it car still ran the same so i thought the maf went bad changed that still issue keeps going. It throws out black smoke when you press the gas. it seemed like a vacuum leak when it first appeared but it wasnt cause all hoses are connected and it seems fine.
Issue:
1. Sluggish
2. Really rich
3. Misfires
4. rpms stay at 1400 and you can hear the motor not firing right.
Changed checked:
1. coil packs and harness no issue there
2. injectors fine
3. fuel pump delivery is good car gets fuel
4. maf changed with new issue kept going
5. vacuum is fine everything is connected
6. really dont know where to turn at this moment cause im out of ideas
7. checked the ecu for codes and didn't give any but then again not too sure if it was done right cause stopped checking it once i saw the maf issue.
If anyone has any ideas please let me know i would really appreciate it! If you need more info ask but i really need some help with this!
