How do I find out what the problem is with my car without putting so much money in it? My car has always had a little skip in it especially when going up a hill. Just recently it started skipping, stalling, cutting back, and sometimes even backfiring. I have replaced the crank sensor, egr valve, and coolant temp sensor. I also had a tune up on it last year.

Two things I would check first is spark and fuel pressure.

If OK, then check convertor. It may be clogged.

This year engine had intake gasket problems, so look for coolant near intake manifold.
