hey guys looking for some help....
2007 gxp...bone stock. had my catalytic converter clog up on way home from indy 500. got it home and found out GM covers it till 80,000 miles. they replaced it. drove it out...turned around within a mile. running like crap and stinking bad. they changed the plugs....after 15 miles started running like hell. flashing engine light then on to steady....just like before plugs. throttle body doesnt seem very dirty. valve on throttle barley opens up with gas pedal push until its floored. is that normal? should i start with fuel filter and seafoam? its running pretty bad right now and im stuck so im looking for suggestions asap. thanks in advance if you post to this.
