I purchased a 1999 Pontiac Bonneville from manamara Pontiac in orlando fl., used our 3 ed one. My wife was driving it to her grands and it started shaking and lunged then quit all of a sudden. The car gave no warning and after a bit it cranked but ran rough. I towed it home and changed the ignition coils, spark plugs and a few other things and it never would run. So I took it to starling Pontiac and they said that the plenum that was on the car was bad in fact it had a defect. The service manager told me (roy) that they have had problems with them. GM called me and said they were closing my case from the BBB because it wasn't a new car from the dealer. I explained that I sent it to you them and others to get it noted. This is a saftey hazzard if it happens on the interstate or in heavey down town traffic. I went to michagan and was told there by GM workers that they had the same thing happen to their new car and the dealer fixed it free and it wasn't wnder warranty. It just seems strange that they don't admit they have a problem.M

The car started stalling and I replaced the plugs, ignition coils (3ea), fuel pressure regulator, took to dealer and their is a seal in the intake that have had problems and it leaked water into the cylinders a little at a time and then let go. They knew they had problems with it, they said so. Est cost $1000, then they will see if the engine is still good. So it could need a new engine.

Vehicle would stall when either turning corner or taking foot off accelerator pedal. Took to dealer several times, and mechanic could not find anything wrong. Had alternator replaced. But, problem still exists.

When thoroughly warmed up, from a stop, usually making a turn, the car does not accelerate normally. Hesitates and acts just as though starving from fuel. Happens a third of the time. Anti-knock sensor is retarding engine timing to a negative reading when it should be a positive 20 degrees during acceleration. Dealer has replaced two sensors and the same situation still exists. Dangerous when merging with or crossing traffic.
