Still trying to get this LQ4 build running right. The car wants to accelerate on its own at low speeds and will pretty much idle up to 55-60. Scanner shows TPS at 0%. Replaced the ICV and no change. When the ICV is disconnected the car runs fine. My tuner claims everything is good on his end. I don't think its the converter being too tight as this cam is very very mild at 216/224 114. What else could cause this issue?
Car also has a high idle at times for no apparent reason. When shifting from Drive to Park the RPM's will shoot up to 1500 then die back down after about 10 seconds.
Thanks
