107122, No power below 3500ish RPM...
Posted by bzoss, Dec-12-07 06:49 AM
First of all, I am a fully built, and turboed 420A.
If it can be done, I did it...

Now for the technical. For some reason my car has no power, runs extremely lean, and jutters below about 3500rpm. It just sort of happened while I was cruizing down the street.
Just want to know if anyone has heard of anything like this. I was surfing some old posts and found someone who had a similar problem which turned out to be a bad camshaft position sensor. I replaced mine and the problem persists.
I am going to swap the crankshaft sensor today to see if that my be the culprit. I would assume that either sensor going bad might produce the same results...
Anyhow, while I am changing out the sensor, I wanted to know if anyone else out there had any ideas or a similar problem that they have fixed already.

Thanks!

Brandon

what have you done to the fuel system? Ignition System?

Plugs? Wires?

Throwing any codes?

Letting us know what your fuel system setup is would help HUGE amounts.

Make a list.

Check it twice.
