After messing with the idle screw I took off the vacuum line to the FPR and covered the barb and it seemed to make it idle lower, indicating a richer mixture correct? So that means FPR is working and I checked fuel pressure when I had it in the shop putting the engine in and it read about 30 psi with a little spraying from the pulsation dampener where I had bad crush washers. So that would seem to me decent fuel pressure.

Initial compression tests with a dying battery say that compression is good on all cylinders. So hmm. I'm going to try and change spark plugs because they were pretty black. Wires dont look the greatest either. Will update with pictures of gauge readings and the plugs when I can hook up a jumper.

I actually had to drive mine and experience the problem and then look at gauge when problem was occuring to tell for sure ... mine ended up being clogged filter with rust from rusty tank inside. Have you changed the fuel filter ?

I have not. Might be a good idea though. I was hoping to get all the old gas out first then change it just to be safe but my buddy has one just sitting for his ae86 so maybe I'll try it.

New spark plugs helped a little, still has the one cylinder I can hear. Maybe exhaust leak or vacuum leak

Cant hurt for sure and its an easy change. Did mine and it was like night and day after. Kinda tricked me cause I replaced it when I did the engine and then slowly my performance went in the toilet and I went over all kinds of other crap since I had changed filter already to find out that's what the problem was. After I pulled tank and saw inside I knew exactly what problem was ....

I feel like an idiot but happy it wasn't so many other much worse things. Turned out that I don't know which way our distributor turns. So cylinders 1 and 4 were correct but 2 and 3 were switched. A teacher at the school who dabbles with PFM (pure f ing magic) helped me feel like a fool because of it. But I appreciate it because I drove it all around yesterday, even taking it on a short trip 20 miles away and it was fine.

So onto the next step. Boost leak testing and axles omg axles. I never thought axles could make the car thump so hard

Glad it was something simple!

Now is a good time to take care of all the maintenance crap since you dont have the cost of a motor.

Axles for the front is definitely top of the list though, the more I drive the worse it gets. Its to the point where I am shaking the car apart from about 20 to 35 mph

well i am dumbfounded again by the ole' girl today. turns out 90% of my vibration was front my loose driveshaft bolts :doh: the driveshaft luckily came off at not too fast of a speed to cause too much damage, although i did get a nice thumbsized hole in the through my shift tunnel. that's going to hurt more than anything. slightly bent an ear on the driveshaft flange, but i was able to put grade 10 bolts with lock washers and blue locktite so hopefully this won't happen again.

otherwise after it was fixed, along with my exhaust gasket while we had it up, it drives great, still slight vibration front the front and clicking in the axles, but nothing like before. still have a small vacuum port open so it's not boosting quite right and the idle goes a little low before it catches itself, but otherwise it runs pretty decent.

slapping myself in the head while going to bed again. at least i get to drive it tomorrow
