Hi guys,

I am having an issue with my svt that has been getting worse. I have searched the forums here and have not had any luck in coming up with a solution. The car has a high/hanging idle around 2200rpm when cold but goes away when warm(does this everyday on cold start). The major problem I am having is it has an intermittent stumble when getting off the highway or after idling for a period of time. The stumble is almost like it is starving for fuel and usually clears up after 10 or 15 seconds or after a good rev or two. This has been an issue since I got the car several months ago but only happened about once a week so I didn't think much of it but it happens every time I drive the car now almost.

I have a predator tuner that came with the car and I have a P2196 rich code.

A little more background on the car it has the stock airbox, external pcv unit, off-road cat pipe and a magnaflow exhaust. I have changed the plugs and wires and checked to see if the coil connector was damaged or had damaged wires and nothing. I thought maybe it was a fuel pressure regulator or an injector but don't just want to throw new parts at it to fix the problem unless I am confident that could be the issue. I am not sure what steps to take next in troubleshooting and I appriciate any help or advise anyone can offer. Thanks!

Sounds like tuner promblem. The orp will make the car run rich. Try putting stock tune back then reinstall predator see what happens.

Removed fuses and gave it another shot. Was able to get the stock tune loaded back in. I will drive it today and report back with an update.
