surgeing now gone ...still shifts a little hard,,,will try adjustment on modulator after it cools down...way to close to the exhaust manifold to chance,,,probably why everyone has this problem...design flaw or maybe vaccuum modules like 800 degree neighboring parts...not

I have an 89 pontiac Bonneville and everything on my car is original except for 5 internal pieces and a few external. Recently we had a series of problems on the fourth of july my car was running just fine we get to the fireworks show i kill her start to start her back over and she wouldn't crank (this is after all day my driver's side door wouldn't open.. after she wouldn't crank that started opening again and hasn't messed up since) but what it did that night was basically i putted it back to the house. I took it to the shop they swore it was my spark plugs.. nope nope.. then it was my catlike converter.. still not a fix. After my muffler fell off now the only problem i have is once i start hitting 40 and she kicks back down in rpm's she will start vibrating real hard at me as long as i stay on the gas for the majority it goes away. (its real hard to explain its one of those things you just have to drive it.) If anyone has had the same problem or any idea im up for it i just don't know whats going on and please don't say junk the car she is my baby and pride and joy i have more sentimental value in that car then money can buy!
