I think I would start with simple stuff first like check your plugs and see if they are fouled maybe you got a bad plug wire or distributor cap or rotor.It could be missing a little.Is the check engine light on?You can use a jumper wire on the scanner plug under the hood to read the codes by the check engine light in the dash those cars have on board diagnostics.A chilton manual shows you how and what the codes mean.
