iluvdrt Posted August 23, 2004 Share Posted August 23, 2004 This problem has been haunting me for a while. It has become so bad I am beginning to hate my suby. 87 gl10 ea82t 5 spd wagon. Basically after the car warms up anything over 4 psi boost will cause the car to decelerate and pour black smoke out the tail pipe. It jerks a lot like it is hitting fuel cut. I think it is electrical because when the car is cold it runs great. I have done the following to it to no avail: new ngk spark plugs gapped .045 new wires new coil (oem) cap and rotor are newer. they appear to get glazed after cleaning then going for a drive. cleaned injectors(seafoam) new intake(old one leaked air past the maf) new pcv valve new coolant temp sensor new o2 sensor always 93 octane new fuel fiter I am at ends wit here. It is not throwing a cel, and the ecu has been cleared. I am very frustrated to the point I want to sell the car. Please help. BTW it mostly does it in 2nd gear.

calebz Posted August 23, 2004 Share Posted August 23, 2004 Its running way rich.. I had a similar problem in Feb. Turned out to be the MAF. Gave no code and I did everything you did. Eventually just started pulling known good spare used stuff out of the garage and throwing parts at them damn car until it worked right. Link to comment Share on other sites More sharing options...
iluvdrt Posted August 23, 2004 Author Share Posted August 23, 2004 Wouldn't a check with the multimeter be able to tell that? If so I will check it. Hopefully if it is bad someone will have a maf they can sell me. Thanks for the tip. Couldn't it be the fuel pressure reg? Or do those not go bad very often?

WJM Posted August 23, 2004 Share Posted August 23, 2004 The pres reg wouldnt do that. Ive got 2 good MAFs at home. Or you could sell me the car. 4wd, right? Link to comment Share on other sites More sharing options...
oobnuker Posted August 23, 2004 Share Posted August 23, 2004 Moosie had this problem when he got his turbo wagon - turned out to be a real simple one: the little hose that goes from the turbo to the plenum atop the throttle body was loose - it should be pushed on all the way to the little stop that is machined into the plenum. Worth a shot - and free! His car seemed to do exactly the same thing. Link to comment Share on other sites More sharing options...
iluvdrt Posted August 23, 2004 Author Share Posted August 23, 2004 Thanks for the help. I will check the hose and the maf as well tonight with a fluke meter. Assuming it is the maf that is bad, WJM, how much would you let one go for? Link to comment Share on other sites More sharing options...

iluvdrt Posted August 24, 2004 Author Share Posted August 24, 2004 For a new one...USMB cost is $509.33 Id let this one go for $30. SWEET!!11!!! I did.n't get a chance to check it because I was to tired(gym>me), but I will. If it is bad I will hit you up on that. You are the man. BTW, I am still pricing your stickers. Sorry about the delay. I have a lot less spare time now. I am going to the px today, I will check there. Link to comment Share on other sites More sharing options...
