hey there. i just got myself a '90 sunbird for $500 canadian and am having some slight problems. well its not really a problem... the engine seems like its misfiring and sounds like it struggles a bit. usually this is in the morning when the engines cold. i replaced the distributor cap, rotor, spark plugs, and ignition wires. also just did an oil change if that matters. my dad tells me it might have something to do with the computer chip but i dont know anything about them. if anyone has any advice and if you know how much a new chip and what its called(i've seen ppl mention eprom's and ecu's) well if you can help me out that'd be great. thanks
PS: if you need more info about the car just lemme know
