My 1998 c1500 4.3 5 speed just developed a problem tonight.
I went out to get a pizza, probably 7 or 8 miles from my house.
On the way down, i thought i felt it buck, like the motor lost for a second. It ran fine the rest of the way.
On the way back, it did it several times. It seemed to do it just about every time I shifted into 3rd gear in the city, and the rpms were 2000-2500.
It did it coming up a hill on the highway in 4th gear also.
This is a new GM engine I just installed a week and a half ago. I also installed a new fuel injection spider.
Just looking for suggestions on things to check. A mechanic friend of mine said could be a crank sensor going or a fuel pressure problem.
