If you have any questions or concerns, please don’t hesitate to let me know. I appreciate your patience and will provide responses as soon as possible. Thank you did they check for spark and injector pulse or do they just like to replace parts without troubleshooting?

Interesting
Automotive Expert
that's the first thing they should have done.

They put a second mechanic on it the 3rd time I took it back. They changed all those parts and didn’t fix itDo you think the maf could be bad and causing misfire
Automotive Expert
no. it's not the maf. did they check for spark and injector pulse?

I don’t know
Automotive Expert
ok, without me knowing that then all I can tell you is you need to check for spark to the #3 cylinder and fuel injector pulse to the #3 fuel injector.

I got a po102 and a po113 from auto zone po303
Automotive Expert
and if there's spark and injector pulse then you need to check compression for the #3 cylinder wait, you said p0303 and nothing about the other codes

They basically told me they can’t fix it at Belle tire after they canged the parts
Automotive Expert
because they don't want to fix it. That's the trouble with mechanics today. if replacing a part doesn't fix something there have no idea what to do.

The other codes are new today from autozone scanner
Automotive Expert
you need to check for spark and injector pulse. for the other codes, you need to test the mass airflow sensor take it to a shop that actually will test things instead of throw parts at it

The second mechanic said my Chevy doesn’t hae the computer like the rest that gives him the information
Automotive Expert
wow. he should not be working on cars if he said that I cant do the tests for you from here. wish I could. I will send you all of the tests that need to be done. please standby

They cleaned the fuel system too
Automotive Expert
cleaning the fuel system doesn't do anything except cost you more money. (see attachments)

I am not sure what computer he was talking about, it gives a history of fuel injector performance. He said mine doesn’t give the history
Automotive Expert
Ok. please take it somewhere to have the testing done that I sent to you. that is all I can do for you here. find a shop that will take the time to do the tests. thank you

the air sensors will not fix the misfires? I have a mechanic I can schedule with and wish I would have called him. I didn’t know they were guessing at Belle tireThank you
Automotive Expert
no, the maf will not cause only 1 cylinder to misfire they were guessing. yes

How many miles before I have to worry about timing chain or belt? I have also been burning oil1-2 quarts between changing
Automotive Expert
you have a timing chain, you don't have to worry about it. as far as burning oil, that's why a compression test is a need also

Thanks again
Automotive Expert
you are very welcome. please stay well.

The most common cause for a P0440 code (https://www.yourmechanic.com/article/p0440-obd-ii-trouble-code-evaporative-emission-control-system-malfunction-by-jay-safford_2) is the fuel cap seal.
