My car has demon's and needs help in a big way!!! I got the tranny from Alan at Dirty Dog put in and was so excited to drive a SC that would run properly. Not a chance as there are to many issues and I don't know what to think or how to fix it. I swapped the blower, plenum and DIC onto the 94 auto that just got the new tranny installed. When we went to start the car it was running really rough and figured it was a vacuum leak. The car's cat on the driver side started glowing red hot. Shut it down let it cool and started again. Thinking it had bad gas I put some more in and the cat wasn't hot anymore, red hot that is. Took the car for a drive in the neighborhood and it stumbled and drove poorly but if you gave it 1/2 throttle it ran just fine. At this point I figured I had a vacuum leak and called Mike and drove the car down to his house to check it all out.
Driving to Mikes the tranny started slipping in OD. Great not even 30 miles and it's slipping. Plus when you put it in reverse it feels really strange like it is fighting itself. I get it to Mikes and we replaced tightened the egr plate. We found a vacuum hose that was sounding like a fog horn and the car was still stumbling running like crap. Then we noticed that when we gave the car some gas that the car went out of vacuum and into boost 5 to 7 lbs depending upon the amount of gas you gave it. Weird. How does it show boost in neutral.... clogged exhaust? Bad O2's?
We noticed if it started running poorly, after a few minutes that when you shut the car down it would run better for a bit then you would repeat that process and it would continue. So when I had to come home when it would start to loss power, I would be giving the car gas, boost is climbing and the car would have no power. It would stumble, sound like a truck drive like crap then I would throw it in neutral, restart it and I could accelerate again.
Then something really weird happened. The car would accelerate on it's own. It would rev up to 3.5k I would throw it in neutral and it would climb to 5k and I would shut it off. Then start the car again, car was getting gas like I had my foot on the gas but I had it behind the pedal to stop it from accelerating and the pedal was doing nothing. I wasn't moving but the car would rev and then after a few minutes it felt like someone was trying to floor it but the pedal was doing nothing.
The worst part was the tranny on first glance feels like it has very soft shifts and starts slipping on the highway the minute it go to much gas. Luckily on the way home there was a lot of traffic so I was doing 30 to 50mph on the way home.
To sum it up
Cat on driver side got red hot, got a little better but still hot.
Car makes boost in neutral or park
stumbles and will lose all power after being driven for a few minutes, restart and repeat process to get home.
Accelerates on it's own then it acts like it is getting floored
tranny slips
Two nice SC's and they both won't stop causing me trouble. Now I guess I have to switch everything over to drive the 89. Spent 2600 on a tranny that slips but I am hoping that it is somehow related to these issues but I don't know why OD would slip.
Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
