Hey everyone. Been reading here for a while but finally needed to post for ideas.
2004, 130k miles.
Had issues with misfiring a while back.
Replaced plugs.
Replaced Coil #5.
Replaced fuel pressure sensor on rail (the old plastic broke when I tried to remove it, so replaced it)
Replaced EGR
Cleaned MAF
Cleaned throttle body
Fixed an issue where someone had previously not attached intake properly to throttlebody and had allowed a bit of fresh air directly at the intake side of the throttlebody, as well as fixed an improperly installed air box that also allowed quite a bit of fresh air past the filter.
It had been running well after this for about 4 months. though run infrequently.
In the last 2 days, a trip on the highway, then coming down to street speeds, it went into limp mode.
There was one instance of a misfire on 5, but that was perhaps an older reading still in the memory, or perhaps not.
I switched coils 5 and 6. Reset everything.
Now I get these errors:
P2104 : the engine control module (ECM) activates this code when it detects throttle control issues that require the throttle actuator control (TAC) system to idle (I assume this is just saying "hey things are screwed going into limp mode)
P2100: an issue with your accelerator pedal position (APP) assembly, a faulty throttle position sensor, or general throttle motor control issues
P2107: malfunction within the throttle control module processor; the throttle actuator motor fails to operate and this is detected by the Engine Control Unit (ECU)
P2110: the engine control module (ECM) is detecting major failures in the throttle actuator control (or TAC) system. This causes the ECM to go into failure or ‘limping’ mode and forcibly limit the RPM
Also, I pulled plug 5, and it appears a bit lean. No oil present.
Does this just sound like a TPM to you folks or perhaps something else as well? There was a TB error back there somewhere, but when things go wrong lots of stuff throws up codes. I can post those if needed, but now it is these 4 that make an appearance after I clear then run again. At least for the moment.
I'm hoping someone with experience in these motors can point me in the right directions. Thanks!
