1990 chevy 3500 engine troubles
I recently bought a 1990 chevy 3500 with a 454 7.4l motor and auto trans. 4wd. now i bought it with these problems hoping i can fix them. i got the codes out, its
code 43 knock sensor
or electronic spark control circuit fault
The symptoms are, the truck doesnt accelerate worth a damn, has terriable gas mileage( i know its a 454) when i shift from park to a gear, the idle drops to almost stalling and then picks back up. i also have a service engine soon light
Would replacing the knock sensor fix this? i was told that code will retard the timing. This could be the cause of all my problems right? thanks

The cheapest way to get a significant power increase over a stock 2.5l, would be to pull it out and put in a 5hp briggs & stratton engine.
