DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!

Need to clean out throttle body on 2002 chevy trailblazer

Throttle Problem

Well 2002 will be port injected,so the throttle body only adjust air flow.Try cleaning Mass Air Flow Sensor and replacing your fuel filter.Make sure that your air filter is clean.If you havn't had a tune up in 100,000 miles then it's time.It could be the TPS ,but would try the others first.Well hope this helps,and good luck.

2006 trailblazer 4x4 4.2, stalls while driving. Engine shuts down, whenever and wherever it feels like it. No pattern other than about every 2-5 miles, has worsened to this point over last 10 days....

ok well try this when it stalls see if spark is present and if it is not and it cools down and starts then you might need to replace ignition control module good luck
