Vinny: that is precisely what I have decided it is. The only bad thing is that the timing on the V8 S4's is on the back end of the engine, so I have to try and get it to my office and get it up on the lift to get to this sensor from below. it is pinched between the cat and the engine block with only a few inches of room. But I guessI iwll just have to wait until Monday or tuesday when the sensor comes in to get it installed.
JM: Thanks for the shop name. I have never had a shop work on my cars aside from things like alignments. I was completely lost trying to think of where to tow to yesterday (before it started up again). I was at the point I was going to have her brought to Fred LAvery and just be prepared to take the abuse they were going to dole out. Now I will have someone else to go to.
A little personal background here on myself. I am 28, married, one kid, live in bloomfield hills and am a Mechanical Engineer by training and position. I work for a top 50 supplier mainly an electrical parts supplier. I have the S4, I just sold my 69 Spitfire and am currently looking for an E30 convertible to replace the spitfire, mainly so the kid can come with if we take the droptop out. We also have an T5 05 S40 which isn't abad little ride from time to time. I have previously owned 1982 Diesel Rabbit 5-speed, 1989 Diesel Jetta 5-speed, 1990 pontiac sunbird convertible auto, 1996 A4 FWD 5-speed 2.8, 1998 Explorer sport auto, 1999 Mercury Cougar (reasonable heavily modded) s-speed, 2004 Explorer auto. I have done engine rebuilds on the sunbird and the cougar and most if not all other maintenance/repairs on all of the other cars.
