1989 pontiac firebird problems..NEEED HELP

i got a couple problems .
1) she shakes when i accel or slow down to fast or i hit a bump in the road when accelerating.
2) the diagnostic computer cant read why my service engine soon light keeps coming on.
3)i need alot of replacement part for her.
4) i need a diagram for a intake manifold gasket replacement i got the new gasket i jsut dont know how to do it.

CAN YOU PLEASE HELP ME>>>>>??????

Shaking can be caused by alot of thing's, Motor mount,tranny mount,out of balance tire or missing or damage suspension part or missing engine. And so on and so on. Have you tried to get codes from her by jumpig the diagnostic terminals or is she just not giving any?. What type of parts do you need so I can try and tell you where you would find them usually at better deal than most of the usual places. Also do you have TPI or TBI so I can try and track down some intake diagram's?

dude i got a problem shes is smoking from the rear of the engine by the fire wall and she is smoking from the valve cover that the oil pours into .. and the radiator is overheating at the same time and it smells like she is burning tranny fluid ... and my exhaust when she starts smoking like that pours out some greyish white smoke...
:screwy: :banghead:

Well you didn't get a good seal for the intake manifold, You have to pull it off. Make sure you get rid of all traces of old gasket and makes sure you put plenty of RTV sealant grey stuff on there don't worry about over doing it. Also a little smoke is normal cause some oil usually splatters on exhaust but then allow 24 hours to let it set before you start it. Let me know what happens.
