I had an ECS kit put on my car in June. The car had 15,000 miles or so when I got the kit and ran perfect. Ever since getting the kit it has been non stop little problems. Recently my check engine light has come on and stayed on. The car has started sputtering really bad, to the point to where I don't drive it. You can't get into the throttle. It has no power up top and feels like it just wants to fall apart. I have contacted the shop where I had the work done and have received no response in almost a week. It's really aggravating being ignored by a shop that you gave $6500+ to. My car has sat in my garage for over 3 weeks because I don't even know if it's safe to drive. I don't know what is wrong or what to do. I was able to drive it over to advanced auto and had the codes read. I have attached images of all 14 codes it pulled up. Can someone please help with this? Thanks!
Looks like you might have some injector issues causing the o2 sensors not to sweep properly. First thing I would do is check the connectors on the injectors. They might just be loose. If they are on good, you'll have to start digging a little deeper. Maybe swap some injectors around and see if the misfire moves with them.
In addition, maybe replace your upstream O2 sensors. Are you MAF or SD tuned?
EDIT: In short, these are your codes
P1133 - O2 sensor replace
P1153 - O2 sensor replace
P0201 - like the guy above me said goes along with P0208 just another cylinder
P0203 - like the guy above me said goes along with P0208 just another cylinder
P0208 - like the guy above me said
P0300 - refer to checking injector and replace O2 sensors...also check ignition wires and spark plugs
U0073 / U0140 - that one's tricky not too sure...IIRC you had issues in general connecting to the car in the past. I would have took car to dealership for this issue before going to heavy into modifying the car. Sounds like an electrical issue.
A few days after I got the car back it broke down and the guys from the shop came and looked at it and it was a loose injector connector. Usually when it would start sputtering I could turn it off, wiggle stuff and it would start back up fine. Not this time. I just want the freaking car to run right. I never imagined I would have this much trouble, especially going to a reputable shop.
I didn't know about any connection issues until he was tuning it and it kept disconnecting from his computer.
