I have been having alot of miss fire codes on my car. It is a 1996 se with 150000. What could be the reason it miss fires??

 

When is the last time you had a tune up?

Plugs&wires. Not sure if you have the coil packs, or straight distributor. Might be a faulty injector leaking too. I would start with plugs and wires if they haven't been changed recently. I think DiscoMike has a link for some good 8mm Magnacor wires. Also run a can of injector cleaner through every 3k to 5k miles making sure you are running premium fuel through at all times.

 

So, as already asked, what sort of tune related work has been done on your truck, what fault codes are you getting, what octane gas are you using?
