n54 injector HELP!!

hellafast · 09-29-2014, 12:38 AM

As I was hoping on the freeway tonight after the 49er game my car felt like I was loosing traction at about 3000rpm and the SES light came on. Luckily I live about 3 miles from the stadium and managed to get home, i scanned the codes and have a misfire in cylinder 1 also got the following codes. P0301, P29F3, P29CD, H2F8F. I am pretty sure its an injector problem but would really like some impute from you all.

no one??

Those look similar to the codes I had when one of my injectors went. Mine got really stuck as was shooting gas out the tail pipe. Any other symptoms?

29f3 could be a low pressure sensor, it's an easy diy, do a search on here.

Quick update, it ended up being a coil so we replaced it but also found a bigger problem. My oil fiber housing was leaking pretty bad too so now I need to dish out more cash to fix that. I can say bye bye to upgrading my intercooler lol.

Glad you fixed it. Unfortunately on these cars maintainance > upgrading.
