I was trying to look through the forums but I couldn't find enough info. I have a 1989 sc and the vacuum is at 14 at an idle. It runs bad. Literally no power, like I can't even get it up a hill. Misfires and lots of exhaust smell. Through all of this there is no check engine light. I replaced the tps, knock, and idle air control sensors. Still nothing. I checked for leaks all over and came up with nothing. I dropped the down pipes off of the exhaust manifold to check for blockage and still the vac never changed. Even though there is no check engine light, could the MAF be bad? I can't believe I can't figure this out!! Most poeple have a problem where the car just doesn't run as good as it could and they can find the problem. Mine runs so bad, I can't drive it. It also seem like, at idle, if i floor it, it would take like 3 second to get to 5000 rpms. If I only give it half throttle it goes up faster?! Can someone please help me!? I don't wanna give up on it. I just put 9 grand into it. Please help!
