Question about 1983 Oldsmobile Delta 88
I have taken it to a mechanic, put way more $ into than i paid for the car. I took the catalytic converter off of it, had no immediate problems. Then it got to wear once it warmed up, it would start missing, like it was out of time. Took it to a local mechanic, he went over it, and over it and came to the conclusion that there was a sensor out somewhere, it would cost me, for him to find it. he recommended that i switch it over to old school, new manifold, distributor, and carb. Any help would be greatly appreciated.. I could go either way to get the ol girl runnin..sensor or switch it over, i just need little advice.
Check the exhaust manifolds. On a lot of the engines there is a little vaccuum operated valve that is supposed to help the engine warm up faster to reduce emissions. A lot of times it gets so rusty that it gets stuck and will make the engine run rough after it warms up. Had it happen on my 83 with the 307, so I disconnected and plugged the vaccuum line and made sure the valve was open. Also check for a stuck/bad egr valve or other vaccuum leaks.
