Ok so yesterday I had my truck retuned to turn off the rear o2 sensors. The shop said they couldnt tune my diablosport chip so I had to get an SCT chip...which I did. Now when I step on the gas from a complete stop it feels like its going to stall out, it hesitates for a couple of seconds and then takes off. Its fine once I'm going but from complete stops it wants to stall...I'm calling the shop Monday to let them know, but does anybody have any other ideas?

By the way it didnt do this before I got it retuned!

 

its all in the tune, they need to fix it.

 

yeah, like troyer needs to fix mine before i wind up with a trashed block from all that excess fuel.

i'd suggest sittin on it for today and then having them fix the tuning, dont let them give ya any bull****.

 

Were you getting black smoke coming out from your pipes because of excess fuel? I noticed that on mine too, is that what that means? Im guessing its harmful to your engine?!?

 

lol thats an understatement bud, yeah theres a ton of excess fuel (black smoke) from my truck. i have a vid up trying to show troyer (he didnt watch it) how damn rich my trucks running. if your too rich and your washing the oil off the cyl walls yes thats VERY bad.

 

But, if your vehicle has hi mi. then you might want to check your throttle position sensor. It is know to have a similiar issue when going bad. When bad it has a dead spot just off idle.

Hey I have 52k miles and I had a check engine come on that indicated the throttle position sensor, this was of course after the tune. Could it be something they tuned or does the sensor go bad?

 

replace the sensor and go from there
