Your friend at MoonBuilt Garage led me here. IAC is carp on my Sniper Q-Jet. IAC starts out very high and once operating temperature is met/exceeded the IAC goes to 0 and idle jumps up 15-1800.

I installed a Terminator X system on my 85 Cutlass supreme with a 355 and a TH350. I had a shop do the work since it involved a new tank etc. After getting the car it ran great but at least once a ride the car would stall while coming to a stop. Initially I thought that the ECU needs to learn my engine and that this would stop, but it didn't. I thought that I had to adjust my idle speed to make it higher than 850(more like 950) to stop it from stalling but then I found your video. I just tuned my IAC just like you said. Mine was initially at 0-2 when at hot idle. When I started your tune procedure and my car initially warmed up to 167 and started to "learn" my IAC was hanging around 8-10 so I thought I was good. I waited like 10 more minutes until the fans ran about 2-3 times and then cranked my throttle and my IAC dropped down to around 0-2. From there I started to back out the screw a 1/4th turn and pop the throttle until i got my IAC to around 7-9. I am going to try to drive the car tomorrow(I dont have time today) and hopefully this resolves my issue with stalling. The car already sounds better at idle now that I tuned the IAC, it used to surge before and the AF ratio would get really high momentarily. Now it just hangs out smooth.

Hi Daniel, Generally speaking a back fire either through the throttle body or the exhaust is a timing issue. The Iac is high because the system is trying to keep the engine running. So, my suggestion is to go back to basics. Pull the plugs and change them, then re-index the distributor. Double check your firing order. I had a Mopar that drove me crazy with a backfire. I thought for sure it was the Sniper. Nope, I had a crossed plug wire. It is easy to put blame on the Sniper because it's new and computerized. But I would go back to basics first. Then check all your sensors thru the handheld. Good Luck, Troy

I am struggling with Holley Sniper. No problem on cranking. But issue is once I step on the throttle, the idle stays up. It will not come down unless I shut the engine off. I am sure I have a setting off. But I am a novice when it comes to these updated system. Any guidance is greatly appreciated.

@troykane

Жыл бұрын

That sound like 1. basic throttle return (spring or linkage) hanging up. Check that first. Or the IAC holding the the throttle open. When you cycle the key the throttle returns. Look at the hand held and read the Idle Air Control at start up. Then again when it's wram over 170. Then throttle up and if it stays high read it again. Chances are that you'll see some high numbers. That means the IAC is holding the throttle open. Go thru the process to reset the IAC. Good Luck

This is the best video I have seen on the IAC adjustment. I am curious you are abl to start the truck before the handheld boots up. I have never been able to do this. I have to wait until the screen and pump primes. Any suggestions on what I can do so I don’t have as long of a wait.

Basically where ever it is right now. Add a full turn. What you are doing is moving the throttle out of reach of the IAC. So the IAC reads Zero. At this point the engine will be revving pretty high 1500-2000 RPM. Then slowly back the screw off to get in range of the IAC. Then continue to back off to get the range you want. Hope this helps. Good luck with the project, Troy

Ok this stuff can be a bit challenging. And doing things remotely is hard, but I will do my best. Think of the IAC as a small motor that can open or close the throttle blades as requested by the computer. When the IAC shows Zero the computer is telling it to close the throttle. When the IAC is, say, at 10 it has partially opened the throttle and could continue to go higher ( open more) to say 20 or go lower to say 5. In your situation, the IAC motor is at Zero The computer is wanting to close that throttle. You want the the IAC to open that throttle to create an idle condition and have the IAC be in control. Meaning it can raise or lower the throttle. Question 1. Do you have the idle set in the Handheld? Question 2. Have you checked for vacuum leaks? Question 3. have you checked the function of the IAC in the handheld? I hope this was a helpful answer. This is a tough thing to do over the computer. Best of luck

Mine works, then it doesn't, I'll be driving, all is fine , then pull up to a light and the engine surges to 1150rpm (from 750) and the car surges forward. I usually put it in neutral, and rev it, it still settles at 1150 1200 rpm until I pull over and shut it off. My IAC reads 20 (I've never seen it go higher) and stays there... I usually just go home and second guess why I ever installed this thing.
