I have tried everything I could but can not seem to find what is causing my throttle response delay. It chokes/delays every time I press the gas pedal at any rpm. Response is horrible. Car does drive and can be driven hard to near redline where i left off just fine.

ECU- Tried 3 different times with 2 ECU that are working and no luck.

Timing- Checked and everything looks fine. Checked 3 times.

Wiring- Checked 8 times and recheck. All wires are done right.

Fuel system- Changed out pump and filter and still is not the problem. Regulator works and car does run rich while driving so everything is running.

TPS- Checked and tested and it works

ISC- Tried it and tested it and it work. Even putted it onto a friends car and worked.

FMIC hard pipe- no clogs.

Leaks- See no leak. Hand checked all hose.

Spark plugs- brand new

oil- brand new

Unknown sounds- None. engine idles 100% perfect like nothings wrong.

Aparently my check engine light does not work so I can not jump any code. All wiring is correct. I will have to get another dash to find out whats wrong.

swap a cluster that works and check for codes stop wasting time trying to figure out whats wrong more then likely you just have to replace the 90 cent bulb behind the check engine light in the cluster.
