Weird Problem

dothedew1654 · July 24th, 2008, 02:14 AM

My car has been having the weirdest problems lately. when im accelerating slowly in the low rpms, it will backfire and hesitate really bad but if i floor it, it clears itself up just fine. Any advice?

Also, my rpm gauge has been acting funny. It will sometimes stay in the same spot and other times jump around randomly. Any advice?

The last problem is, when im floored around 4000-4500 rpms, it will just stop accelerating. it feels like it won't let me rev above certain rpm. The other day i was on the freeway in 5th, and it wouldn't let me above 2500 rpms. Any advice?

mine was having a similiar problem it would miss and have poppong sound but when I would accelerate it would go away. I had a bad injector.

Well i fixed the hesitation in the high rpms. its still hesitating in the low rpms and the tach is off. but when its warmed up it won't pop at all.

TFI module, if your tach jumps around and falls off, at the same time as the engine stumbles.
