Two of the top fan mounting bolts are missing.

car had been sitting in garage a few years ,without starting

but now has no power when you hit the gas.also dies how do i fix the problem

The compartment around my gas cap retains water. No water has entered the engine but I'm worried that this could happen.

any problems with knock sensor

the car will not turnover

Bought it used from Ebay. I think the security system is preventing it from starting. What do I do? Do I need to change any codes or bypass the security system?

I just had my car diagnosed by a garage saying that it has a condition called 'torque converter lock up' and this is the reason that the car shakes / vibrates violently when on the Hgwy under load @ approx 2200 RPM. The car has ~102K miles on the odometer. He suggest that the torque converter be replaced. He is not a corvette mechanic, but he is an excellent mechanic having many many years of JEEP experience. Does his diagnosis sound reasonable, and what would be a ball park cost for this job?

engine will start has ruff idle an will not take fuel, motor will die

car been sitting i took out old gas . put new spark plug.it try to start but not

The car will start and idle but as soon as you press on the gas pedal the engine stalls. Getting engine code 42 (ignition contro module) and 33 (MAP sensor). The problem first appeared while driving, engine was running fine, and died immediately. No warning. I have changed the distributor cap, coil and ignition control module (still getting code 42). Checked MAP sensor by plugging it on another car, senor worked fine.

Any suggestions?

have replaced the fuel filters, fuel pump, fuel pressure regulator, does not loose fuel pressure when it dies and it will start right back up. what to ck next?
