Started my SUV to leave for work this morning at -11C ( 12 F). The Beast started fine.
I should mention it has 293,000km ( 182,000miles). Everything original except.... thermostat , fuel filter, air filter and plugs and changed a iso-converter valve in the transmission valve body 4 days ago.(Transgo kit) Its a 2003 trailblazer.
I pushed the gas and my top speed was 40km/hr and the engine service and Reduced engine power light came on!!
Took it to my bros shop and we got codes .......
1221 ( throttle position sensor)
1635 ( 5 volt circuit)
I have seen other posts about 1221 code coming up but none that have 1221 with 1635 and so that is why I posted.
I left the truck turned off for 3 hours and when i started it up again it ran fine !! Its midnight now and have driven another 50 km with no troubles.
I will start by cleaning the throttle body in the morning. I will keep everyone posted of my progress.
