Issue: Car is stalling after warms up, has bad misfire it feels like but no CEL code.
So far I had the following parts replaced:
1. Secondary Shutter Valve + Bolts
2. Radiator
3. Spark Plugs
4. Battery + Alternator
5. Clutch Kit
6. Coils
Cleaned or looked at:
1. Throttle Body : Cleaned
2. Cat : Looked at, I came to a stop at the end of a drive and sounded like small shards of metal rattling in a tin can. I had my mechanic look at it and he said the Cat is fine.
I brought it to my mechanic who knows and owned a rotary (Rx8), I trust him as he won't call me back until he is 100% sure of the issue. He said that my fuel injectors have gone bad and it is best to have them all replaced.
Autozone wants $150 just for 1 injector, my question is, is there anywhere I can find reliable injectors for a much more affordable price? My mechanic is also charging $300 for the labor, which compared to Mazda doesn't seem all that bad.
The car will not make that tin rattling sound from under my feet until after the car has been running for a while and starts to run hot, it will also run fine until it runs hot, then it will continue to try and stall out. It also has a very bad gas smell from it when just turning it on or driving. Windows up or down its horrible. He said the compression is good, and my injectors will cause these issues but I would like a second opinion along with a source of where I could get these injectors cheaper and if there is a DIY page somewhere on this topic.
Thanks!

sounds the cat is bad.
I know you said they checked it but something isn't right there.

#6: What coil did you replace it with? OEM? Aftermarket?
did he send them out for cleaning / flow testing or he's just eyeballing this thing?
did he check the fuel pump?

do you ever drive in the evening?
if you do, and the car starts having these symptoms, pull over and look under the car quickly. If the cat is glowing red hot, there's a problem.
As for a compression test: that's always a good idea if someone is having hot start issues (car won't start if the engine has been run for a while) as that's typically a sign of a motor going out. I'm not sure we're there. yet.

UPDATE: There was issues prior which caused it to stall out quite often. Mazda wants $1,800 for just the parts (All 6 Injectors), but I found them on rockauto wanting about $250 for all 6 + the o-ring and fuel filter which the injectors are remanufactured OEM.
