scenario: car warms up, when i stab the throttle sharply (as in a rev match downshift, or just getting revs up to take off from a stop), it responds, hesitates (will not drop revs), and responds again (almost as if i am blipping the throttle twice).
car specs: speed density (no MAF), relayed 044 fuel pump with less than 20k, 550cc injectors with less than 20k miles on them, new fuel filter with less than 10k miles on it
before you ask: I have done the following
- ISV/IAC
- TPS
- vacuum leak test
- spark plugs
- replaced all coil packs (2.0T)
- fuel filter, air filter
many have been suggesting that i replace the ECU. is there anything else i should try?
