Thanks for your expertise. Im getting a new coil and module and have the cam sensor checked out. And I do have a vacuum gauge but not on the boost gauge. I might just also replace the ecm with one that is known to work. I'll keep you updated, with any updates.

The fan quits because the wire doesn't fit the connector very well

my boost gauge doesnt show vacuum, my fp stays the same....When my car is running good i can uplug the cam sensor and the car runs fine, when its running bad if i unplug it the car runs worse .  Another thing i noticed is the car is getting a little harder to start, only when its hot outside when its cool out i will start with a quick twist of the wrist. Thanks for all the help with this problem!!!! Ohh and it doesnt matter if the car is hot or cold ...this problem comes and goes when it wants to.

When the car is running good at idle the scan master numbers are
O2 ~ 700`s- 800`s
Maf~ 04
Blm~ 133
Clt~ 184
Volts~ 13.6 to 13.8

When its running bad ......
O2~ 00 to low 100`s
Maf~ 04
Blm~ 138
Clt~ 184
Volts~ 14.0 to 14.3

All the turbo and intake connections are tight. The plugs are new and gaped properly. the a/c compressor is not on the car that's why I have the bypass pulley on till I can get it running correctly. The egr diaphragm is popping down. if I unplug the cam sensor it runs worse. The fuel pressure is 32 psi with vac line on 38 psi with it off, and its steady no matter how its running. All the grounds are tight. I know its hard to diagnose the problem when you can't see it. So if you guys are still stumped I might have to get a pro logger So I can share better data with everyone. But anyways.... Does anyone see any thing wrong with my data so far.........?

I have a few problems with my car but ill start with the most weird problem that I have. first ill let everyone know what has been done to the car. its a 1987 we4 turbo T all stock but...... scan master, hot wire kit, walbro FP, TT chip burnt for 91, adj FP reg, Ls1 MAF w/ TRANSLATOR, heated O2 sensor, a/c bypass.sometim es my car runs perfect then all of a sudden the idle goes off like it has a miss ....it falls on its face under boost ..... regular driving it sputters when the throttle is pressed lightly. Then all of a sudden it goes back to running flawless      im confused !!!! I don't know whats going on, Or how to troubleshoot this. another problem that is going on is that I have very small sparks that jumping from the alt to the alt pulley where the belt is, but Its so small it can only be seen in pitch dark. there is another small spark jumping from the a/c bypass pulley to the belt as well. installed a ground kit to relocate the ground from behind the heads w/ no luck. I really need a turbo buick experts to help me with this problem. Im ready to  my TR. please help !!!
