All,
I'm getting an odd "surge" when I drive. She idle's fine and revving seems to be smooth, but for the past week or so, when I drive and start to accelerate (cold or warm) I get a hesitation consistently. I replaced the head gasket about 8 months ago and all was running fine. I decided to test compression and got the following starting from the water pump (#1 and working back to the firewall #4) 1 - 90 2 - 85 3 - 89 4 - 90 I didn't do a wet test, only dry. Attach the tester and crank it with the starter for a few seconds. Check, and do it again to confirm results. Looks like the low end of acceptable, but I'm an apprentice in this area. Any help is appreciated. Thanks, -Thomas |
