Hey guys, wondering if anyone has any ideas on why my 91 350 refuses to run right
On cold mornings when you go to turn it on it'll immidietly die, but fire back up easily, but under any kind of load, up hill or towing a trailer, it'll bog and act like it's running out of throttle, to the point that with my 2000lb car trailer it's hard to keep 65mph
So far I've replaced
Fuel filter
Fuel pump (getting 12 psi at the filter)
Rebuilt throttle body as well as a new regulator
New o2 sensor
New ICM
New CTS
New ECM
New knock sensor
New injectors
All vacuum hoses are good
New egr
After breaking down and taking it to a mechanic with live data he verified that all sensors was working properly, but the engine is running super lean, and the computer was pulling more and more fuel
Something like 120 was stock and it's running at like 165ish trying to pull fuel? I've lost the paper
Anyone have any ideaa
