ENGINE AND ENGINE COOLING

 My 97 monte carlo z34 started dying on me whenever i came to a complete stop and after i had been driving it for a while. and it would shoot forward after i started it again in neutral(the only way it would start). placing myself in the middle of intersections unwillingly, i would have to start my car and make sure no cars were coming any way or else i would have crashed! now my car is completely undrivable and dies whenever i hit my brakes, i took the car to several mechanics since this started and have had the following changed/repaired: upper and lower intake gasket set, throttle body gasket, thermostat, spark plugs and wires, air filter, numerous vacuum leaks, valve covers. *tr

 My 1997 chevrolet monte carlo was recently diagnosed with an intake manifold gasket that needs to be replaced (due to leaking of engine coolant). two mechanics informed me the repair costs would be between $800-$1000. after further research, i discovered several general motors vehicles between 1996-2002 had this same problem. though no official recall was done, gm did publish a technical service bulletin regarding this problem a few years ago. i know canada has filed class action suits against canada gm concerning this issue. the car only has 120k miles on it, and the bluebook states the value to be around $2200. does the state of maryland have information on this issue requiring gm to perform this work under some kind of warranty? *tr

 My 1997 monte carlo is in need of an intake manifold gasket replacement. why isn't this a gm recall? the repair cost is $800 and my internet research shows that this is a prevalent problem in gm cars. my car is unsafe to drive until the repair is complete. the engine could catch fire or freeze up while driving. gm needs to recall these defective plastic gaskets immediately before someone gets killed! *jb

 I took my car to bob mcdorman chevrolet in january (vehicle was still under warranty) about several concerns i had. one concern i pointed out was that my car cranked a long time to start. i also had them repair my driver seat belt, that would not contract, had them check my brakes because they were taking longer to stop on wet pavement and they were squeaking. well, needless to say, nothing was found to be wrong with anything except my seat belt. i also reported that there was a ticking sound in the morning when i started the car. they told me some ticking is normal on a cold start. on 03-29-99 i took the vehicle in because the service engine soon light kept flashing and staying on, the idle was very rough, car was missing terribly, sulfur smell was present. bob mcdorman chevrolet replaced three plugs and wires. i took my car back on 4-14-99 because the car was running rough again. bob mcdorman chevrolet replaced the other three spark plugs and wires. on july 26, 1999 i was driving on the freeway @ approximately 65mph. i lost all power and my car would not restart. i called chevy on 07-27-99. i was told to take the car into a dealer and they may assist with reimbursement but could not guarantee it. i called several chevrolet dealers but could not get my car in for a week. bob mcdorman was called and i spoke with the service manager (steve alexander). he told me that they couldnot go back on the warranty because this was a new problem. i explained to him that my car was running rough all along like before in spurts and i felt the warranty should cover what i had it in for before. to make a long story short, i took my car to a garage, they said it was the alternater ($453.16). now, in the beginning of september, my car misses after it is started and still idling rough. took it back to the garage and was told it is now my fuel pump. i contacted
