Hello people!

I ran into a problem with my Z about 2-3 months ago
Im mainly concern about this CODE P2138 which cause my car to go into Limp mode with no acceleration. (this happen out of no where) driving/idle

info about my car

Turbo by Boosted Performance Single Turbo, was left in the garage for roughly over a year or so (army life) left it with my parents.

I think all the Evap code is because of my turbo. ( from what i was told)

I check all my wiring and switch my pedal, i also cleaned out my throttle body.

P2138 - Throttle/Pedal Position Sensor/Switch "D"/"E" Voltage Correlation. <---

P006A - MAP Mass or Volume Air Flow Correlation Bank 1
- Was told due to Turbo

P0443 - Evaporative Emission System Purge Control Valve Circuit
- Was told due to Turbo

P0448 Evap Emission System Vent Control Circuit Shorted <-
- should this be showed Shorted? could this lead me to a voltage correlation to P2138?

Any help would be great...

Check your left and right side intake manifold sensors - mine on occasion unglugs once in a while. It looks pluged in but if it out 1/2" will cause everything to go into limp mode.

Just give them a little push to make sure both on each side are securely plugged in. As soon as it plugs in you will hear a click.

you need to just clear codes - and you should be good.
