A couple days ago I told you about an '88 Chevy 3500 I test drove. It has the 3-speed automatic. The truck got a new 350 crate engine 30,000 miles ago as the original engine somehow got antifreeze in the oil and wiped out the bearings, (head gasket?). Anyhoo, the owner has been dumping money into it for quite a while now trying to solve a stalling engine problem. It likes to stall at low rpms, especially when it's cold. However, it restarts with no problem. He has receipts for new plugs, wires, distributer cap, O2 senser, etc. The shop tried a new throttle body fuel injection unit, and still the problem persisted. I am thinking the problem must be a vaccuum leak somehow. It is also a little pokey shifting into high gear, particularly before it's warmed up. Vehicle has had regular servicing of engine/transmission. Truck has 139,000 miles on it. It looks well cared for. Now, after all those details....Does this auto trans require vacuum from the intake? I'm wondering if when the engine was switched, they somehow missed a vacuum hose, thus explaining the stalling problem and the pokey shifting into high gear. I am mostly relaying the details I was told as I only drove it about two miles. The stalling problem was evident in that you could tell it wanted to kill, but with a little fiddling with the gas peddle, it would stay running. Engine runs good, with good power. Sorry for the lengthy post. Any suggestions? Thanks, Glenn F.
