Got a 99 Silverado 1500 4x4. It spits and spudders
after the motor gets warm. It wasn't water in the
gas. Cats have been cut out. Any ideas what it
The first Step is, Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.
Its showing the o2 sensor and the sensor in the transmission but it can't be the transmission.
Then that does leave the 02 sensor which sends a signal to the computer to (help) control the fuel mixture.Next, check fuel pressure at the fuel rail using a gauge read the PSI.. it could be failing and have lower specs than necessary.
