So I found a solid, one-owner '96 Sierra C1500 with the 4.3 and 4L60-E, and went to check it out yesterday. The truck has 225K on it but has obviously been pretty well maintained. It's an ECSB, which would be a nice addition for when I need to take the kids to school and the wife has the van.
It has a very odd issue, though: When I took off with it, as long as I stayed at half-throttle or less, it ran great. No issues at all. But as soon as I floored it, it was like hitting a wall. No acceleration, no downshifting, just sputtering.
The dealer told me he'd just gotten it out of the shop, where they did a tune-up including cap and rotor. I did note (and he did, too) that it has a loud fuel pump. Wondering if that might be the problem.
I'd like to think if it's a simple fix (sensor related or even fuel pump), I might still be interested in the truck. But if we're talking a transmission issue or something larger, I don't want that kind of headache.
Any thoughts???
