My 91 T2 is running like ****. I think it is a vaccum leak but i am not completely sure and i think my tps needs to be adjusted. This is what the porblem is, when i try to start the car when it is cold it will start then idle for maybe a sec and then die if i dont keep my foot on the gas. Also I use to hit 12 lbs of boost in 3rd gear and now i only get 8 lbs and when i let off I hear my blow off valve, but then it sounds almost as if another one goes off. I am pretty sure i have a vaccum leak, but i am down here at school and it is kind of hard to work on. I am going to attempt to do some work on it tommrow. Anyone have any suggestions on what the problem could be?

AHH update....got in my car today to go to class and it wont even start....anyone live in Orlando that is good with RX7s I just dont have the tools down here. I am about a mile away from UCF

 

**** dude, that sucks. A good way to check for vacuum leaks would be to go buy a can of carb cleaner or tb cleaner and spray away at your engine bay. If there are any leaks your rpm's will increase when the cleaner is sprayed over them.

 

When you try to start it, is it cranking at all? Is the starter giving a good effort, or is it toast?

 

RX is back with a 900 fee from mazda for fixing a crank angle sensor and a few other things. I know i got taken but i really cant do to much down here at school. When i got it back it still didnt idle well but it started. So I knew I had a vaccum leak. I found my intake tube after the Air Flow Sensor had a crack so I fixed that, but didnt help the vaccum leak, so i knew it had to be something else. I got some starter fluid sprayed it around and realized it was my BAC leaking. I got some gasket sealant, took off the BAC and gooped the hell out of it (I know it isnt the best method, but I dont have many tools here at school), but the fixed my problem. The car is back better than ever, right now i am pulling 18lbs of vaccum on my jspec engine. Ahh finally a smooth *** running RX in my possession.
