Hey guys,
I need some help.. This past Saturday I did the ultimate mods and put all new gaskets in my TBI. Put it all back together and it started up and ran fine. Started it on Sunday and drove it around town, no problems. Monday morning I got to start my truck and it has a terribly rough idle, I attempt to leave for work and when I gave it throttle it would just cut out and try to die so I limp it back home.
After work I go to the parts store and buy a new IAC. Start up my pickup, it now has a nice smooth idle. I take it out for a drive and still same thing. So I got back to the parts store and buy a TPS. Take it for another drive and same thing.
I don't want to keep throwing money at it but it's my daily so I need to get it figured out. I get a code after driving for so long but it's code 44 which is O2 Sensor (Lean Condition) which makes sense because the engine acts like it's not getting fuel.
The rebuild kit I bought didn't include a new fuel pressure regulator but I am not sure that is the problem either. I have also read that it could be the EGR solenoid and to unhook the vacuum line to see if it runs better and sometimes it may but then they say they replace their solenoid and they still have the problem.
It seems like multiple cylinders are misfiring so it almost makes me think it could be an injector but I am not sure.
When I am driving, if I put the pedal to the floor it'll get some power but still not 100%.
