My 87 T seems to have a real light surge while cruising. I can really notice it in 4th at about 50mph.
Last night I was cruising at 50mph and it was surging, I left off the gas and then gave it about 1/4 throttle and it sounded like it back fired a little then it took off. It wont backfire any other time but right after cruising and then jumping on the gas.
vacuum is 18 at idle
fuel pressure is 45 with the line off
I'll have to try and get my scanmaster readings while it happens
Any simple things that I can check?
