Hi all. I recently did some work to my G, I plan on boosting or supercharging soon. So while I had all the intake manifolds off ( which I bored out upper and lower in the process) I switched out the injectors to a bigger size. I got it tuned with ecutek but after it got out of the tune shop I keep throwing a map Sensor code or a vacuum leak. I’ve checked, double checked all the possibilities for a vacuum leak.. My guess would be the car is running to rich. Has anyone had a issue like this or possibly point me in a direction to fix it.. maybe a FPR might help? Any suggestions would help, thanks in advance

 

What's the code?
Running rich won't set a MAP code.

 

It threw a p0108

 

Would you know of a reason why I’m having throttle response issues to where it kinda feels like a limp mode. But it doesn’t happen all the time, and to where it would throw a MAP sensor code or making it dirty to where it won’t run efficiently. I cleaned all the sensors, intake tubes, filters. And it’s somehow still throwing a MAP code.

 

Contact the shop.

 

Do you have an idea on what it could be...?

 

Either its just a coincidence and the sensor failed or the harness got damaged.

 

I did happen to change out the sensor before. And it still threw the code. After running for 20-30 minutes it would go into that safe mode or kinda like a limp mode and not give throttle response. I’ll contact the shop see if they could check it out. I put a volt meter on it while I was at the tune shop and it was running high, I believe like 14.5 for the map sensor...

 

Map sensor should only see 5v if I recall correctly.

 

Ya, that’s what I’m sure of as well.. I’m unsure on why it’s running high. And I’m unsure on why it’s getting “dirty” to throw the code
