timg Posted September 22, 2003 Report Share Posted September 22, 2003 Here's the deal. Above 3000 rpm, when I hit 5 psi, the entire car bucks. It feels like the car has full power, then nothing(like all fuel has been cut), then full power again and so on. Once I break 5 psi, there aren't any problems. The A/F ratio goes completely lean when it bucks. It's rich below and above 5 psi. It almost feels like hitting a rev limiter. If you have any ideas, please let me know!

Redfox340 Posted September 22, 2003 Report Share Posted September 22, 2003 Perhaps a Transmission Neutral Switch. Explains the absolute Lean A/F mixture at 3K RPM's. The ECM will kill out the fuel injectors to regulate engine speed. Replace the switch and most likely you'll be set. - Erik Quote Link to comment Share on other sites More sharing options...
