I have a 1988 trans am 5.0 TPI and i am going threw a few problems with it. I purchased the car like 4 months ago and was working fine when i got it. I did a whole tune up on it. But recently my car is now stalling, for example when i warmup the car in the mornings i rev my engine and it stuters and turns off. When i want too turn in on again the it turns on very weak the rpm's dropp and my oil pressure gauge rise. There is also a clicking sound on the distributor. I gave the car a timing and it still does the same noise. Any Idea what my car could have?
