2009 Chevy Colorado runs perfectly except when coming to a stop. The engine will buck,shutter and kinda catch itself and may or may not stall. I have had the throttle body cleaned, cam shaft sensor replaced, a full tune-up and air filter replace and it just seems to get worse. Started with stalling when making right turns????. It always starts right back up and now it has started to make a rattle sound at stops ( however this may be the catalytic cover? The Chevy dealer thinks its internal and wants 3 to 5 hundred without any proof they will find anything ???

I had one of these before that was doing the same thing and replacing the electronic throttle body resolved it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Tks Did it also make any noises? I'm not sure if the noise which sounds like a diesel engine is from a loose catalytic cover or not?

It's not the cause of the noises but the low idle and engine shaking is what is bringing them out. A broken cat is very possible. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

the vehicle is stock, and not operated in Canada? I remember an issue when you mentioned while turning it was more of a concern, it sounds like a TSB re returnless fuel systems and accumulation of dirt in the fuel rail, If I come across # I will post it - your dealer might look it up fro you... You could - have vehicle scanned for codes, add a fuel detergent - TECHRON or seafoam, an inexpensive step and routine maintenance. JUST maybe will a solution. A second issue could be TCC sticking - try shifting to N when slowing is the problem changed? found some info recall #PIP3333A TSB 03-06-04-030H,

Just about the noise and rule out heat shields: Super common in rusty, salt areas for use on roads mostly. Tap on exhaust parts front to rear for a loose one. Most are spot welded in place which is where they give out. If this DO NOT LOSE THE PARTS! When cool decide if you can drill a hold and screw it back together or I have near 100% luck with the very large worm gear type clamps for home dryer vents made of stainless wrap entire shield in place usually over a converter or muffler but same idea if room. Line it up, snug it up right where it was. This has lasted longer than the first stuff did from new for me! Duly noted it sounds hack but works better than OE. YOU NEED THOSE SHIELDS. THIS IS A REAL FIX IMO vs all new stuff pipe, converters, mufflers or what it cover that can be perfectly good and all new cost a fortune and just do it again. If with screws use stainless as well not regular or even coated with zinc better but will fail too. Pop rivets would work but could fail with heat? T

When I shift into neutral when stopping what reaction would prove it may be the TCC or Torque converter?

A stuck TCC solenoid will act like a manual trans that you forgot to push the clutch in when coming to a stop. It goes away if it is pushed into neutral before stopping. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
