Limp mode again but this time its different ?

ultraslan · 08-15-2010, 05:27 PM

I been getting the limp mode lately.

It goes up to 4500 rpm and wont let me go pass that and engine malfunction . reduced power comes on.

but when I am stepping it slowly it will let me go pass 4500 RPM and go all they way to the end.

Any ideas whats causing this ? thnx

Going light throttle doesn't create boost so you don't hit limp mode

but once you hit boosts, you go into limp mode and get a failure.

If you're 100% stock, most likely the HPFP

But, if you're heavily modded, you COULD have blown off your charge pipe.
I did that once; thought it was the HPFP and crawled home.
Only to pop the hood and see what really happened.

just got exhaust and inter cooler.

dealer changed the fuel injectors , ignition coils.. problem still happens . I hope its the HPFP so i can get it fixed for free!

I would bet its a boost leak from your new intercooler.....Check your intercooler piping.

^^+10. check your charge pipe and retrack the install.

I bet you're running a piggy.
This used to happen to me a lot especially in 4th at 4500.

k726 · 08-15-2010, 10:39 PM

Sounds like a boost leak to me as well. Can also check your stock chargepipe is seated properly.

Bimmer This · 08-15-2010, 11:19 PM

does it feel like it is boosting right before your about get the engine malfunction lamp?

ultraslan · 08-16-2010, 03:02 PM

ill take a look at the inter cooler pipes and see if anything is wrong or looks weird.

mr.5 - whats piggy ?

Bimmer This - yes it does feel right before i hit 4500 and when i hit it car shakes and wont let me go past and the engine malfunction goes on and says reduced power. thnx

Piggy back tune. I'm assuming now that you are not running a tune.

ultraslan · 08-16-2010, 03:07 PM

no i do not have any tunes.

i guess its either the HPFP or the intercooler ?

ultraslan · 08-16-2010, 05:04 PM
