Hi i have a cold running issue my car stutters chokes misfires whilst driving till warms up got a compression test done heres my results
warm compression test results:
1- 100
2- 110
3- 105
4- 105
all in psi
Could this be my issue
No misfire when he had laptop on it it only misfires if i try to drive through bad stuttering as in apply more throttle instead of just lifting off
dont try to drive through it, could damage the engine. Can you leave the car parked up and go into town and then have him plug in when its cold and doing it?
Compression (warm engine, 350 rpm and fully open throttle)
Standard = 142 — 171 psi
Limit = 128 psi
Difference between cylinders less than 7 psi
Your pressures are low and below the bottom limit. Might be worth getting a leak down test done to establish where the problems. Could be piston rings or valves passing.
