Thanks for the post maxthread. Unfortunately you are right, I am just throwing parts at the car. I'm not getting a check engine light, and I put new spark plugs in 10k miles ago. The wires were checked at that time and were supposedly ok. So I'm thinking it's not the plugs or the wires.
I'll get the fuel pressure tested though, that's a good idea. Is there an easy way to test the fuel pressure, or do I have to take it to a shop to get tested?
