Compression testing came out fine. I have 150-160 across the board. Obviously that is not my problem... I didn't think so, but it is good piece of mind and I wouldn't feel "dumb" later down the road if I never did one, then finaly decided to do one and had half a blown motor ;) Anyway, I fired the car up yesterday when I was done compression testing and I kind of have a better idea as to what is happening... I just need to find out why now. I know that my a/f gauge is no true test to a/f ratio, but in this case, it is saying something, that is for sure. I have the gauge probed into the drivers side O2 wire. Once sensor warms up, the gauge starts dancing around and so on. If I hold the RPM's up around3-4k (which is VERY light throttle pressure), it will hold just fine, then about 4-5 seconds later, the a/f gauge drops off of the lean end FAST, and the rpms fall (obviously) and it will sit there caughing and sputtering till I take my foot off, then it immediately goes back to normal, a/f gauge starts dancing around again... it is a little sluggish and towards the lean end for a few seconds (almost like it is trying to catch back up) but then the car is fine. It never hunts for idle, it never stalls, nothing... it just INSTANTLY goes super lean, totaly like a fuel cut, and when I let off... it goes back to normal right away. This seems to be a load issue because at idle, I can rev it quite a bit before it does this, but when trying to actually drive the car, it falls on it's face right from a start bassicaly. Has anyone heard of this before? I checked the TPS voltage and it seems linear, no blips or anything. A few people are still pointing fingers at the meter, but why did my car do the same thing with Anthony's on it then? Any ideas? I feel like a dog chasing it's tail in circles.
