So here is the story that goes with the problem.
I went out to tune earlier and seen a 91 awd out of the coener of my eye. I thought to myself, I have to go by and make sure that is what it was. So I did that, and yes it was a 91 AWD red with the stupid wing on it like the fast and the furious. So I stopped and talked to them. After I left there, I went down the blacktop that is close to me. I did a 3rd gear pull and it felt strong and pulled hard. I looked at the log I took from that run and no knock all the way through the power band. So I turn around and try it again. This time my pc had shut down on me so no log. But when I get to the stop sign it is idling way low, so I tap the gas to give it a rev and see if I can bring it back up. Didn't work out like I was wanting it to. I then pull away from the stop sign and go through first then second. I hit third and laid it to the floor! It took off and did what it was supposed to for me. Then I push the clutch in to coast to a stop and the motor dies. WHY? I don't know! So I coast all the way to my turn and let out the clutch in fourth gear and it catches and starts. No big deal right, WRONG! I got to the next stop and it dies again. When I got to my drive way it did it again. WHY? I know I got a boost leak at the PCV. But it shouldn't cause this thing to die like it is. I am confused about what is going on. I checked all the settings in DSM Link and they are the same as they have been. Does anyone have any ideas? If you don't remember what I am running. 3" gm mafs and translator front mount w/ hard piping Hallman MBC set at 19psi 50 trim turbo 44mm wastegate w/ open dump turbo xs rfl BOV open dump 850cc FIC injectors The last pull I did it had 2.5 counts of knock at 3200 rpm and went away at 4700 rpm. And my A/F ratio doesn't get any lower than 10.00. -------------------- |

UPDATE!!!!
I checked the turbo and it spins freely. I checked the timing with the light and with DSM Link and it is 5 degrees on the nose. I also pulled each plug wire off while it was running 4, 3, & 2 made the motor run worse when pulled. 1 made no difference when pulled. I then checked my plugs. #1 was black as hell, and the rest look like normal wear. So I proceeded to do a compression check, this is how the number went starting with the 4th cylinder. 90-100-120-120 That is what the compression on the motor is right now. I checked the oil for water and there is no sign of water there. I am this [] close to selling it and being done. I have had nothing but problems from the start with this thing. Now it looks like I need a new bottom end for this bitch. I stopped by a friends shop and borrowed his leak down tester. I hooked it up to number one cylinder and It is pushing air out of four. I plug cylinder four and the air gushes out of cylinder three. Plug cylinder three and all the air goes out the intake and dipstick tube. Number two cylinder seems to be the only good one, there is no air coming out of it at all. Now remember this is just me pumping air into number one cylinder and plugin the rest of them one by one. No bubbling of the water coolant either. It was passing air out the oil fill hole also. I am starting to think the worste now. Not a good deal I would say! That is my out come so far. I have yet to pull the head or do anything to it. I will probably pull it out tomorrow morning. As soon as I get it out and find the problem I will post up. -------------------- |
