No power on hills, rough idle

Plugged in a scan tool today and at idle im getting 40% engine load and usually around 18* timing.Fuel pressure was as high as 50 idle and lowest was 38 under load.

How 'bout a compression test to start with, then go from there with other possibilities.

Sailor has an excellent idea. Bad compression on one or more cylinders will cause those symptoms, and if that's your problem you need to know sooner rather than later.

If your compression is good, here are a few other things to check: idle air control valve, PCV hose, coil & harness. All are common issues with these cars.

Turned out my timing was retarded by one tooth, car has power now.For anyone else who may be having this problem i noticed low vacuum, which affected the brakes you had to rev the car or the booster wasnt getting enough vacuum.Also when the car was near empty it would act as if it was running out of gas and i would get the rotten egg smell like my cat was bad.
