Re: Need a 1g DSM turbo expert

Okay, guys, time for a further update. I came to a revelation last night. So, today, I'm putting the boost leak check on hold. Remember when I said that after I changed the plugs, I got her to run, just not very well? Well, last night, I started her and tried to take her for a spin. I couldn't get her to go anywhere. She would not stay running. So, I took the suggestion of more than a few people and I disconnected the Mass Airflow Meter (the one in the air cleaner cannister). While I was at it, I disconnected the battery for a few minutes to reset the computer, thinking maybe that would reset the fuel/air mixture. When I reconnected the battery and started the car, it ran. Not very well, but it ran. So, I'm thinking, "Cool. I just reset the fuel air mixture", and took her for a spin, albeit a very rough spin. I drive a few blocks, then pulled over to reconnect the MAF Meter. I popped the hood and reconnected the plug, then tried to restart her. I was right back where I started. She wouldn't stay running at all. She'd fire and die instantly. So, I disconnected the MAF Meter, and drove her back home.

Here's another oddity of that situation. I replaced the Idle Speed Control a couple of months ago because it was chattering at me like a chipmunk when the key was on but the car wasn't running. I was thinking that was the reason that she was running so crappy. That didn't fix the problem, though. The new one I put on still chatters. Well, I hadn't noticed at the time, but last night when I disconnected the MAF Meter, the ISC stopped chattering. When I plugged it back in, I noticed that the chattering had been gone and came back when I plugged the MAF Meter back in. So, after a series of disconnects and reconnects of the MAF Meter, sure enough, whenever it was unplugged, the ISC was quiet. Whenever it was plugged in, the ISC went crazy.

So, what does that sound like to you? MAF Meter's bad, right? Couldn't just be caused by a vacuum leak, could it? I'm going to alleviate any possibility of that tomorrow. I'm going to go buy a spool of vacuum line and replace all of them. Not just because it's running bad. After 13 years, I'm sure it'll do the car some good. I'm going to go to my donor car today and grab the MAF Meter off of it. Not sure if that'll fix it, though. The reason I say that is because the outer housing of the air cleaner cannister on the donor car is missing. So, that MAF Meter has been blowing in the wind for God knows how long. I'm sure that one's bad. But, for free, it can't hurt to give it a go. If anybody has any other ideas for me or wants to confirm my suspicions, I welcome any comments. I'll keep you posted as to what I come up with.

Thanks for everybody's help.
Jon
