2010 Chevrolet Equinox Should I have to pay for them replacing my injector if it didn't fix my problem?
Should I have to pay for them replacing my injector if it didn't fix my problem?
What is your question?
So I took to a dealership and they did compression test and said they performed a fuel injector balance test and found injector was 5 psi lower than the others during test and after replacing the injector found the ecm was not firing 1 injector when warm tested harness and found ecm would not light a noid light meaning after warm the ecm would not fire number 1 injector does that sound right and still charging me for replacing the injector that didn't fix my problem and it was a dealership!!!
What makes this problem better or worse?
It stays the same just misfires between 3-4k rpm

It's done this for about 3 weeks but putting it in shop and want to know if they should run a diagnostic test first then go from there
RepairPal Certified shops can diagnose and repair your 2010 Chevrolet Equinox. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Hello, any time you get a misfire code, you'll want to check for spark on the spark plug and cylinder first. You can accomplish this by swapping coils - does the misfire follow the coil, or stay with cylinder 1? Then swap the plug. Does the misfire follow the plug, or stay with cylinder 1?
If the problem moves, you know where to look. If it stays with cylinder 1, I'd try a base compression test and cylinder leak down test next. I'd say it's more unlikely you have any concern with your ECM or injectors.
