Hello,
Took the car an a long road trip this weekend (4hrs) for the first time since I rebuilt my engine 6mo ago. The car has run fine since the rebuild on trips of a 2hrs or less. About 2 1/2 into my trip I notice a loss of power. By the time I made it to my parents house it was sputtering and backfiring slightly. I looked it over, suspecting a vacuum leak or a hose or wire came loose. I took it out for another drive after it cooled for a few hrs and it ran fine then after about 20 min it started to sputter again??? I left the car at my parents and took my 68 vett home....which is another challenge

anyway, I plan on returning to my parents this weekend and do the followings checks: Coil...I have another one sitting around so ill switch it out, replace the fuel filter, preform the fuel pressure check on the CIS (i'll post the results) Change out the spark plugs since their cheep. Check the distributor, cap and rotor for cracks, and check the timing. Also, the fuel pump is new but is a cheep one...might be heating up and not working properly. I replace almost everything new when I did my rebuild. I did not replace the WUR however. Have I overlooked anything I should check? Has anyone had a similar experience? I did alot of searching and found similar threads but no success stories?
Thank you!
Alan
