Check Engine Light On
2005 Chevrolet Trailblazer (Page 1 of 2)
This problem may be covered under warranty. Ask your Chevrolet dealer.
CarComplaints.com Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.
This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.
Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

Check engine light comes on randomly. Some times it goes off in a few miles and sometimes it stays on for days. Scanner said it was the #2 coil. I had it replaced. A couple days later the light came on again. I replace the coil again. Same thing. Exchanged the # 2 coil with the #3 coil, same thing and the scanner still says #2 coil. I will not be able to pass the emissions test in May. If the check engine light comes on, it's an automatic fail. Now what???
Update from Apr 25, 2017: Check engine light comes on when idle. Scanner states #2 coil. I replaced the coil. The light still comes on. Scanner says #2 coil. I replced it again. Light still comes on, scanner says the same.
Mechanic switched the #2 & #3 coils. Light still comes on and the scanner still says #2 coil. Mechanic said it's a factory defect, but Chevy won't recall the vehicles. I'm on a fixed income and can't afford to just throw my truck away and buy a new one. My plates are due for renewal in July and the truck won't pass emissions if the Check engine light comes on.
Please help!
