a1 with a 7730.
Car developped a dead miss at high throttle over 4K RPM. Like it hits a rev limiter... I'll have to check the ign. module and grounds and that stuff. was running soo well the other day.
I think my fuel pump just took a crap.
I'll fill the tank with fresh gas and see what it does.11.92 @ 122 MPH 3400 91 Cavalier Z24 Intercooled S/C. -totalled-

Don't fill it all the way... even with a fiero's tiny tank they get heavy!Originally posted by Mars View Posta1 with a 7730.

My car only has 30 useable litres before the pump gets LOUD. Even though the tank holds 40. Kinda annoying.'89 Firebird, 3500 Turbo, T56, 9-bolt/4.11

OK, the high load miss went away after a bottle of lucas inj. cleaner... ? lol. I'll see how long the fix lasts.
And on a good note, the 2000RPM surge was just a throttle stop screw issue. It was allowing too much air in at idle, adjusted that and now the car runs very nice.
Dyno soon I hope.11.92 @ 122 MPH 3400 91 Cavalier Z24 Intercooled S/C. -totalled-

The miss is still there. I'm pretty sure its fuel pres. related.
so...
decided to order new fuel pump. 5CA400 was 71$ from fuel pump.net, but then the 5CA400HP 255LHP was only 121$ so I went with that one instead.
it'll work better with the Precision billet58mm I just got...
