WELL it's still happening. Still no CEL and it feels like running out of gas. Thinking the fuel pump next. Wondering if it could be the throttle body actuator ? I would think if it was one of the monitored parts it would throw a code or illuminate the CEL. When it does loose power it happens...

So I installed the new parts and seems to have fixed the problem. I suspect it was either the fuel pressure regulator or the plugs. Has a little more pep and climbs hills with no problem.

I have a pressure regulator , fuel pump modulator and new plugs ordered.

SO I finally got around to doing a scan. No codes found, no CEL. Kind of think it may be fuel related as there are no codes. What systems are not monitored my the computer? Going to do a fuel pressure check. Thinking maybe a fuel problem, pump-regulator-filter-modulator?

Got home , 2880 miles with the power loss thing going on. Most noticeable when going up hills and when the temps are a little higher. Got to Oregon where it is a little cooler and it seems to run better, but still happens occasionally.

I think the APPS is bad or the TPS is bad. When driving it will run fine then just like a switch was turned off the engine looses power. Then after driving a while the engine runs fine again. It will cycle like this and it doesn't seem to be related to how I am driving. I am on a long trip so I...

If its a cat will it run good then run bad then run good?

I just got a 1999 . While driving after it warms up it losses power, no shaking like a missing cylinder the motor just looses power. While on the freeway it will got from 70 down to 60 and will not accelerate unless floored. No cel showing. While going uphill at 65 today it slowed to 45. Still...
