rev limit at 4500 rpm

[black96ti]

I dont know if its the rev limit kicking in early or is the damn car just bogging at 4500 rpm but it will never rev pass that no matter what i do in gear or not . Who knows how long kits been doing this help help before i get rid of the car!!!!!!!!!!!!!!!!!!

The rev limiter is at 6500 rpm.

Does the car have a manual or automatic? When was it built (month/year)?

Does it have any other problems, for example, in the ABS?

check everything in the engine

Wouldn't this be an ECU fault?

[black96ti]

its not my ti thats having problem its my 93 318is yes it has a abs light on and i got a code 1271 which state coil number one has short ground or open circuit i just replace the coil and reset the ecu and did the stomp test without cranking up the car and it show code 1444 which is no error and code then i crank it let it idle and now its throwing the same damn code and still no 6500 rpm rev . The redline still at 4500 rpm. The car ride normal but when i get the cel 1271 my car has a rattle in the front right under the valve cover sound lick a chain tapping but if I shut off the car and crank it up it sounds normal sometimes how can i have a short in my coil number one

The limp mode in some ECU lowers the rev limit to protect the engine...

seeing as its been cold in GA i would guess that your engine needs to warm up, does it still let you rev only to 4500 when your engine is warm?

I was going to say something with the disa since it opens around that rpm, but maybe a short in the wiring to the coil then? If you're getting a code, I say investigate that further..

Pull the coil and plug boot off. As mentioned above, it's been cold in GA and it's possible the boot may not have a good seal and moisture is getting in there causing a short. The boot may be worn out / cracking (may not be visible).
