Ok guys, I've replaced the cap/rotor/coil/wires/and plugs. The car misses out at lower RPMS, and when going down a slight hill in 4th gear, it seems to miss out as well(going about 40mph). The only thing left in my ignition system that could be causing the problem is the distributor. Any ideas? Oh, I replaced the ignition moduel as well.

This is just a guess but did you check your Throttle Position Sensor and did you check the timing.

Don't forget to check your vacuum hoses. They could be getting hard and cracking, considering the age of your car.

I checked the timing, I haven't checked the TPS. I'll do that, I'm sure there's a writeup on se-r.net for it. Thanks

I'll take a look, I tried to find some silicone vacume hoses localy, but I couldn't find any. Maybe I'll just buy some cheapo regualar vacume hoses and put those on there.

I just checked the TPS, its dead on where its supposed to be. And the timing, I just set it at 19 about 2 weeks ago. Any other ideas?

I tried ot check the fuel pressure from the line going back to the gas tank(so I could test the FPR) but its not working, I can test the fuel going INTO the FPR(50lbs, seems a little low)but not coming out. Please help guys!
