Engine stalling out HELP
Recently finished the 5.3/4l60e engine tranny swap out of a 99 Silverado in to my 72 Blazer 4X4. I swapped everything i could get my hands on...
Enigine, Trans, Wireing Harness and PCM, Under hood Fuse Block, Fuel lines and in tank pump, Instrument cluster...Everything. Had the Vats removed by Brendan LT1SWAP. The swap has been running great. Better then great. For one full tank. Filled up with gas headed for the lake and got 2 miles and began to stall under a load. If I accelerate, go up a hill, even power brake the thing wants to cut out. occaisionaly sputters and jumps, but tends to stall out. Starts right back up, idles like a champ, sounds great just does not want to take off. WTF???????? I really need some help on this one. checked the O2s, Maf, Fuel pump, nothing seems to have come unplugged. Just don't know what to look for next. |
