Car: Firechicken Engine: 350 + 30 over, 400 crank Transmission: autotragic, stalled Axle/Gears: not a one tire fire, thank god! | mystery problems
Ok, to make a long story short, I borrowed my car to my brother for a week and now that I got it back, it feels really down on power. I used to be able to floor it and roast the tires, now I don't get a chirp. It idles funny, and takes a long time to start.
He swears he did put premium fuel in it since he has been driving it and ignition timing is still where I had it at 8 degrees, not stock 6 degrees. But it still feels super low on power. Mileage also seems to be lower but I can't varify that. It feels like now there is a 2.8 in my car instead of the 350 tpi.
What should I look at and what could cause all of these problems at once? I thought maybe the TPS but how would that effect starting and mileage? I'm asking for any suggestions that you may have, later, I'll pull out the fuel pressure gauge and see what it says. I have no fuel coming out of the regulator so I know that isn't ripped. I know the racetronix pump is still good and the powermaster alternator has more than enough power to power everything. Any ideas?  | | | |
