Ok so i have a 92 camaro, about 2 mths ago it started occasionally having a hard time getting started in the morning. When it finally would start i have to keep my foot on the gas to keep it running. The engine sounds very bad like a blown engine really or an engine with no exhaust. It does have an exhaust leak by the way. At first this would happen only 1 time a wk or so, now its like everyday. Just replaced the plug wires and cap and rotor. Cranked fine yesterday but didn't want to crank at all this morn, just turned over and over. Finally had to give it a break because i didn't want to kill the battery. Went back out a minute ago and pumped the gas like crazy and it cranked, once again extremely rough. The thing is that this only happens when you first crank it in the morning, the rest of the time it cranks as it should and sounds great minus the exhaust leak, even runs good. So i'm thinking next maybe the MAP sensor. Any help with this is greatly appreciated as this is currently my only car.
