my e30 revs to 4500

[2.5-12]

which DME does your car have?

how old is your fuel pump, fuel filter, FPR, how many miles on the injectors?

[e30-325]

as far as i know the fuel pump is the one thats been in there for years. just ordered a fuel filter an hour ago, FPR was new in november as were the injectors. 19lb injectors cuz they were cheaper than stock at the time lol

I see -- and which DME do you have? the 153, 173 or one of them fancy schmancy 380s?

the 19lb injectors shouldn't be a problem because the ecu can re map but if its a 153, you may have problems and thats my bet at the moment (although I do reserve the right to change my bet at any time if I think of something else!) haha

This is an electrical problem, not fuel related. Have you tested both your CPS and TPS? I know you said the TPS is new, but i've seen "new" ones not work.

After those two, it leaves you with DME.

[e30-325]

CPS? would that be crank position sensor?

i bought a new one from bav auto in november of last year. havent checked it though, only cleaned it

[Philo]

Crank Positioning Sensor.

I think its because your car has rust, and it doesn't want to go so fast the body panels will shake and fall off. Like self preservation. LOL

I say electrical. He rebuilt the whole head and didn't hook something up correctly. (I was the one who helped him properly wire his dizzy to get it to start wooo!)

Thats because the dizzy was labeled wrong cuz it was from ebay. SORRY my car isnt from colorado where theres no rust. :neutral:

you must have a launch control lol

NEW DEVELOPMENTS!!!

lol
well i was driving home and my car really starts to wig out. like im at 75mph with about 3300 rpms. its bucking, acting like theres no fuel but the car doesnt die. basically when i floor it from 75 in 5th gear it wont go anywhere at all. but i had to get home so i downshifted to 4th to be at like 4k rpms at 75 and it drove fine. the whole hour drive home it did this so i just stayed in 4th most of the time. then i started to see if my rev limiter was still there, but it wasnt. it actually revved to the real limiter. NOW does anyone have a better idea?

[bimmer_E30]

Could be a broken rocker arm? make a video.

i would say a bad fuel pump too.

[e30-325]

i pulled the valve cover and everything was fine, no broken rockers. I also don't think this is a fuel issue. I'll check my CPS today with a multimeter and get back to you guys.
another thing i dont know if i said, sometimes when the CEL comes on, its like theres a loose wire and the CEL flickers like crazy. im determined to find this wire if there is indeed a loose one

[e30-325]

i checked my cps, afm, and coil and they all checked out fine.

BUT tonight i was driving home as usual and the weirdest thing happened, i was at like 3k rpms just cruising and the tach just dropped off the face of the earth to 0 rpm, the CEL came on and it caught itself again and went back to normal cruising speed. the car stalled for the second the tach plummeted but it came right back to life.
ANYONE?
