02 Monte Carlo SS no power, heartless
I am working on a 2002 Chevy monte carlo SS 3.8L.
the car has absolutely no power, it is heartless.... The check engine light is on, pulled codes P0300, P0480, P0131. I replaced the Plugs and Wires - that did nothing. So i figured the catalytic converter was clogged - so i gutted the cat and still has absolutely no power. what else could be the problem?

Re: 02 Monte Carlo SS no power, heartless
Do you have a noticeable misfire, not enough info to know what " heartless" boils down to. 0300 is random misfire, 480 is a cooling fan circuit and 131 is low 02 voltage.

Idling, I don't notice the misfire but when u give it gas u do.
The cooling fan circuit has been fixed, disregard that code.

Re: 02 Monte Carlo SS no power, heartless
Ok under load you have a misfire, bad injector, low fuel pressure, bad coil, all can cause this.
