Tried all i can think of and can't figure it out. Im running an 02 bottom end with a top swap from a 97.
Anyways my problem is when i'm driving after i let off the pedal from accelerating the rpms will drop down to about 1600 rpm, and stay there until i brake which then will drop under 1500 and eventually stop at 1100 rpms. I have to push pretty hard as the cars trying to push through the brakes. After i'm stopped for a while it idles down to around 750 rpms. BUT, if i try to take off to fast the car lurches almost dies and the takes off. The car also seems to run rich/er
Things i've done to try and fix this is obviously
-check for vac leaks
-replace MAF
-change front 02
-Take out rear 02 so it reads just oxygen
-Change ICV
On another note im running SD headers and i also have an exhaust leak. Theres a 2.5in band clamp on the first joint which is slighty too big, and im running just the u bolts on all other connections. Im also getting some KR too where i don't think i should
When i first had the tune done i don't remember it doing this, and there was definatly 0 knock.
Any help is greatly appreciated! This car is starting to really piss me off!
