im not sure how to describe what it did but I will try. I was driving this morning and the car was moving at a constant rpm then for a split second it lost rpm (not power) like a hiccup. on the way home it did it twice. im thinking its a fuel issue. maybe a warning my fuel pumps about to go. it has been whining when the tank gets low. any thoughts?

 

If you're worried about fuel pressure then pressure check it first. Which of course needs to be added into a tbi since the factory felt you'd never need to check a tbi. There are a few suggestions on the boards for what to do about that.

Personally I'd be looking into spark first. Bad module? Poor connection somewhere at the engine ground, distributor, coil, etc?

 

x sounds like ignition to me

 

I can see it being spark. I will check my connections first.
