Hey guys what’s up, new to the club, and I need some help .
It’s regarding “limp mode”
And how in the hell Can I fix it,
TPS replaced and calibrated
MAF replaced
Throttle body cleaned.
And attempted to relearn throttle body to no success.
Surely not an ECU issue? Right?
attempt at relearning TB lead to it working for small time then back to limp mode. Can anyone help?

What engine codes do you have.... that should be step one in asking for help.

P0300,p0100,p0110,p1121,p0300,
i have the plugs to fix this misfire just haven’t gotten to it yet,
but those are all of them

Don't change plugs to fix a misfire unless you know for a fact the plugs are bad. It's not common to just foul a spark plug. P1121 has something to do with your throttle. I would make sure all the wires plugged into your throttle are in good condition.... ANYTHING wrong w/ the throttle will give you limp mode.

It was the plug forsure I pulled it and checked it was bad.
its driving fine again.
no jerking
but will still go back into limp mode
ive checked all my TB wires

Look up my posts.. from fixed this issue

Check connectors and replace with spliced pigtails.... they crumple. Bmotorsports is a great & inexpensive resource.
most likely it’s your APPS.
look online I found a new part at parts geek for under $140 (DO NOT BUY OFF EBAY)
the only difficulty on replacing this is ... bending the clips and having a tiny socket ... if you get those two things it’s a breeze.
Replace your PCV hoses... cheap fix ... and they get hard and go bad.

PrisyCrisy

Actually... looked up your codes...

cheap and easy...

Clean MAF or replace
change out PCV and hoses...
check connectors on plugs... I had one bust
connector on TPS and APPS and Also throttle motor

if your getting a code for the TPS and you replaced it.... it’s most likely the wiring OR you didn’t calibrate it correctly.

get yourself a BlueDriver Bluetooth reader... it’s cheap, does live checks and explains codes.

let me know if I can help more!

I lined my tps up with the marks I made on my last one
is there a different way??
does it need to be relearned ?

PrisyCrisy

1. I would absolutely order a new pigtail for the TPS and then crimp/ splice that to the wires
be sure to mark your wires.
2. Have you checked the codes again?

PrisyCrisy

You should definitely do a relearn...
Here’s a video on YouTube about it.

Replace spark plug wires too

They will crack under that heat after 100k
