Something is wrong with my RPM's

[Black318IS]

The other day my starter had a bad ground so we had to fix that and now the day i finish getting that all done, I go to take it on the road. Now for every gear the car will not go past 2,500 RPM's. It is a 1993 318IS. If anyone knows what might be wrong lpease tell me ASAP because I need to fix it. Thanks for hte help and ask questions if you do not understand

I was told that the car is running in some sort of "LIMP" mode. We tried cleaning all wire plugs and we just tried to leave the battery disconnected for a while. If there are any other solutions to this problem please reply as soon as possible because I need to have the car done today. Thanks again

Limp home mode= basically a fail safe so you don't damage anything. Try the pedal method to read off any codes.

how do you do the pedal method to read the codes?

[Black318IS]

what is the pedal method, what codes does it fix and how long does it take ?

[Kevin325i]

Takes like 20 seconds. Turn the car to the run setting, and press the gas pedal to the floor three times in a row very quickly. The check engine light will blink out the codes to you.

ALSO, when was the last time your spark plugs were replaced? My car was running pretty good this morning and I decided I wanted to change the plugs cause I didn't know the last time it had been done. Long story short it runs pretty piss poor right now. At about 2500 rpms it stops misfiring, and then at around 5000 it starts it again, it's like the rev limiter, but I'm almost positive it's a misfire.

Replace your plugs, or atleast check them. It's pretty cheap (20 bucks or so) but I think I should have gotten the bosch +2 instead of these sheety autolite double platinum. GO WITH OE.

P.S. Now we're in the same boat.

mine boggs out after 4500. as if i'm redlining allready. and what's with the gas thingy??? i thought it was pressing your odometer first then switching the key to the start position? I will change my sparks coz i don't know when the last time it was replaced. hope that fixes the problem.

[Kevin325i]

Make sure you go with stock plugs, or atleast make sure they're the same temp plugs or else you'll foul them.

I'm gonna pick up a set of the stock ones tomorrow

I'd like to change mine. I have a 97 328iS, what plugs should I install?

[Kevin325i]

I hate to say it, cause it's gonna cost you an arm and a leg. But take yourself over to the dealer and ask them for a set of the original equipment bosch spark plugs. Good luck, hopefully it's not to expensive.

There's also a write up in the DIY stuff to change the plugs, I used the ones with pictures cause it was my first timing changing them on this car. It's pretty straight forward you shouldn't have a problem if you follow directions.
