A month later my P0303 is back?!?! Last time i tracked it down to injector after switching injectors with cyl 1 and code following i changed the faulty injector now in #1 position so the one thats currently in #3 was #1 originally... could my car be damaging the injector?

I got the email notice today. I'll stop by next week and make appointments for my cars.

Email from where? I just bought this car so i doubt im getting it in the mail since i just registered it.

I replaced my injector with another used one from ebay cars idling good now and no CEL im still a bit paranoid. Where can I get injectors cleaned around MA? And I want to do a compression test also for some peace of mind...

Well, if now the CEL has moved to cylinder 1, then your fuel injector from 3 may be bad then (since the latter has moved to cylinder 1)?

 

yes ive parked the car since and waiting for some injectors I found on ebay. hopefully that solves it. im thinking about getting my injectors cleaned any place local to me in Boston, MA?

Try moving the coil pack first. It's cleaner and easier than the injector.

I moved the coil packs when I changed spark plugs. I just rotated injector 1 and 3 and now its barely turning on and not idling shuts off i got p0301 as pending not the flashing cel but its bad im not driving it like this.

i just got this car just put 1000k on it already and the car idles oh so smooth and drives like it should its all stock. then suddenly start idling rough one day and throws a P0303 i made it home short shifting at 2k i was only like 4 miles away.

The next day car turns on fine and is driving normal again. I ordered new oem spark plugs put them on a couple days later and found the coil plug for cyl 3 is cracked. So i ordered a new one on ebay. meanwhile car is driving good still with new plugs idling even smoother id say. then next day again flashing CEl while driving pull over same code let car sit for a while erase code turn it back on cars back to idling smooth. and driving normal did it twice in the 4 days took the plug to arrive so I get back in there replace the harness connector and rotate the coil packs from 1 and 3....

car drives perfectly fine for a day then next day back again started idling a little rough and got worse but no CEL pluggled in scanner and had P0303 pending again. same cylinder parked car hours later get back in it and its driving back to normal.....

this weekends plan is to rotate Injector any other ideas what it could be since its so inconsistent?
