Customer Question

I have a 97 chevy Tahoe LT 4x4 with a 5.7L Vortec motor. When the truck gets to operating tempature and I'm on the interstate or going up a slight hill at about 1200 to 1400 RPMS it studders and jerks then if I floor it or let off the throttle it will act normal. Then after I shut it off and come back say 2 mins later to start it up it hesitates like it has a dead battery but yet the battery is fine. What causes these issues ?

hey how are you

1- is there a check engine light on now ? did you scan it & retrieve fault codes

2- CKP Crank Shaft position Sensor & MAF mass Air Flow Sensor are 2 sensors will cause this & want throw a fault code

3- has it been tuned up

4- have you checked for vacuum leaks , spray starting fluid on intake manifold on a cold engine & see if it surges up

5- can you get fuel trims reading ,long term & short term at idle ?

Please let me know

Thank You
