well up to this point noone has been able to figure this out on other forums so lets see if you guys can help
Ok Audi ran like crap for a month before we got some parts to try and fix it. Would take 15+ start-ups when cold to actually keep it running, and had to drop 2 gears on any hill, couldnt go more than 40mph on the hills I used to do 70-80mph on. Changed the fuel filters also. Found out the O-Ring between the fuel distributer and air box assembly was shot so we replaced that, still ran aweful so we also replaced the fuel distributor. Here is where it gets weird to us.
The two screws that hold the distributor on to the air box we can crank down on and tighten, but if we do the car wont run/start, but back them off 1/2 turn and it will run fine. This would be alright but when you run it from point a to b the screw loosens and makes it run worse and even unable to start once shut off.
Another thing we noticed is when you first start it up it will rev to 2k because of it being cold, but once warm it will spike between 800 RPMs and 1200 RPMs
Now today we started it probably the first time in 2 weeks and the sucker popped off in 2 spins of the starter and ran awesome. Seemed to have all the power it used to, shut it down after a 5 or so minute ride and would not start up. Wont even show any RPMS on the tach.
New fuel distributor
Cold start valve works beautiful
Injectors spraying fuel
Cannot tighten the 2 flat head screws on the distibutor without it shutting off
