Idle problems HELP!!!
#15
I check a few thing night throttle angle look good ready look must everything. Timing was one thing that look like it maybe need changing. At 1200rpm in neutral timing is around 27 to 32 but if u try to go lower timing go down and engine cutoff, If you turn engine over not throttle timing is 0 to 8 and engine try to start but wont unless u give it some throttle. This is a SD tune and short term fuel trim is -27 at 1700rpm but long term is always 0. also commard a/f is 1:01:1 I dont understand that . I also seen if you are at 2000rpm or 3000rpm and put it in gear timing go in the teen's and lower and the engine cut off. I got it in gear one time drove up the road 50 mph truck run great but come to a stop u must keep the throttle on or it will stall. Tuner guys what you think????? Vacuum leak???? Bad tune?????

Guys what you think about a intake leak??? I know its pulling fuel at 1500rpm but I'm look hard and can't find anything making it not idle. I know I can put timing in it to help but below 1200rpm it like you switch it off. I can be at 3000rpm put in drive it go dead. If I put it in gear and almost floor it will run in gear I can slowly let off the throttle to 1200 to 1500rpm it run good in gear. What in hell else can it be???? Help me tuner????
