CHEVY 5.3 K1500 ENGINE CUTS WHEN COLD WHEN FIRST ACCELERATING

Does it seem like when the engine is cold it runs ok, then when it reaches operating temp. it starts acting up? (poor acceleration, stalling) When I had that problem w/ my 93 K1500, it ended up being my oxygen sensor. (causing too rich of a mixture in the throttle body)
Hope this helps, Good luck

check fuel pressure, it has to have 60psi. @55psi it wont run. hook up a fuel pressure gauge and drive it, check fuel filter.

how many miles are on it, if you biuld one it will cost alot with no warranty or you can buy a crate motor from gm with awarranty, i have put in a few crate motors and the run like crazy.

hi, the problem you are having sounds to me like the oxygen sensor " or lambda sensor for its real name" has failed and needs replacing the reason it points towards this being the fault is that the oxygen sensor only starts working once the engine reaches a certain temp so if your car runs perfect from cold but plays up when warm then this is a good indication that the oxygen sensor needs replacing.

Let me know how you get on or if you need further assistance ok

the ignition module is on the way out

Have you checked for any codes? Is the check engine light on? If there is any codes it will give you an idea of what to look for.

check if went from a V6 TO V8 need power two more cylinders

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

the oil depends on how many miles are on it and where you live. In a cold climate with low milage it should be 0-30 or 5-30 with higher milage 10-30 or 10-40 in warmer climates low milage 5-30 or 10-30 higher milage 10-40
