It has about 160,000 miles, I changed fuel filter, spark plugs, spark plug wires, air filter, and 1 of the 2 coil packs.
When the vehicle is cold, I start up the engine and it runs fine until I step on the gas, in drive, reverse, or park. It stumbles really bad until the engine is warmed up.
When the vehicle is warm, I floor it when I get on the acceleration ramp and I noticed it accelerates faster if I let up on it a little bit.
Is it the fuel pump not getting enough gas to the engine?
