You can put a vacuum gauge on it and see what it's pulling at idle, should be 18-20. When I bought my 90is it drove fine, idled a little rough but had NO BALLS, like I would rev it up to 6k, dump the clutch and it would barely chirp the tires. Compression test showed catastrophic loss of compression, pulled the head and found 6 bent exhaust valves. Apparently the PO had snapped the timing belt and just threw a new belt on to sell it. Funny thing was, at higher RPMs you could feel the power come back, because the inertia was pulling the valves fully shut. I drove it like that for a few months before I got up the nerve to do the compression test...Thankfully I didn't throw money at other parts trying to fix the issue.

Understood - I'm here to learn for your experience. Like I said, I'm getting it tested, I just want to make sure I'm safe getting it down to the shop. Rather not spend money on a tow, if possible. No matter what the compression test shows, I'd be surprised to find that I didn't have a vacuum leak and pretty much anything I've done to this point had to be done before I can drive it anyway.

Have a few parts coming in today. I'll get those on and do somethjng with the hood and then get it inti the shop. I'm on the fence about replacing the hood after the fire but I may just put it back on and make the decision when it gets to be "make it pretty" time.

Car's in the local shop. The say the compression is so-so. I think one cylinder is about 15-20% lower than the average of the others but it's still in what the Bentley says is the good range. Makes me wonder how consistent they were when they did the test. I can't imagine the compression being above stock after this long so they obviously cranked it more than what then Bentley calls for. Found several vacuum leaks that we're fixing and they're putting e36 CABs on because I don't have a press. Otherwise they says it's pretty solid. Get it back tonight.

Not like you need a press. I burn them out and use a sawzall to get out the retainer ring lol. Good about the vac leaks tho. Fixing those will make the car run tons better.

one cylinder being 15-20% lower than the rest is not ok, all cylinders should be within 10% of each other. Did they do a wet compression test after that to see if the loss was through the rings or valves? What were the actual numbers? As long as they were consistent with how much they cranked it doesn't matter how much you crank it despite what the bently says, peak compression is what you're judging against.

Yeah, I get that consistency is the key, not the number. I'm wondering how consistent the cranks were during the test. The car doesn't feel like it has a missing cylinder (I drove it in college that way for a while) and the shop owner agreed when he drove it. Not terribly concerned at the moment. It's eventually going to get rebuilt anyway.

I'm more concerned about the all but missing bushings in the rear sub frame (have a 3.46 LSD on the way to go in when I get the bushings replaced) and the fuel/air mixture which still isn't right. Theoretically, the vacuum leaks are fixed now. The brakes feel like it anyway. Anyone have a good way to evaluate the mixture?

Have a buddy hang out the back of the car and smell. Give him a white board so he can write down what he thinks it is and pass it to you while you drive.

I thought y'all knew all the tricks!

I toyed with the AFM a bit and it runs better now but it's still not right. Can't really drive it to see either. Couple weeks and tax returns and get the bushings done.

Hang out in your garage with all the doors and windows closed, run car and see if exhaust burns your eyes. If it does, too rich, if it doesn't you're probably dead.

And then I wouldn't care anyway. Off to read about what to do with my bushings. Too many options and consequences.

unless it's a track car go with stock. Anything beyond that will make it less comfortable on the road and cost more.

I never noticed much ride quality degradation from harder/solid bushings. I did notice a shit ton more noise though.

noise and vibration were the biggest difference I noticed. My ride was already stupid stiff so can't say the bushings make it any more harsh.
