Yamaha F150 stalling

[shoresls1]

New to me boat. 07 F150. It stalls at times when coming off idle already in gear. Shifting in and out of gear does not stall. Only happens when giving the initial tip in with the throttle. Any amount of throttle above idle it does not happen. I have a YDS. It showed the following red codes. TPS and throttle valve position. I literally touched the idle screw and it went normal. I turned the idle screw just a hair and they went normal. No alarms. No codes. Boat runs right otherwise. While this is minor, it's irritating at the wrong times.

1st pic is idle in N after adjusting the idle rpm a hair. Other two pics are the codes I got with key ON engine OFF. If I started the engine they turned off. It is sitting about 700rpms half warm. In water it's solid 600 range.

well crap, pics are to big. The red codes are TPS voltage at 0.00 and throttle valve position at -17.5. Again, start engine and they are .7 and.1 with no error.

It was/is a common issue with this engine, been there, done that with my '06 F150.

I have the updated proper link and sync as a PDF. PM me your e-mail address and I'll send it to you.

Member Rodbolt, is a Master Tech, so pay close attention to his posts as well.

BTW, There is NO idle screw, your likely messing with the two TB single sync screw... Idle adjustment is a PIA, not like a simple carb..

Yes, the screw on outside. lack of technical knowledge on this for sure. I literally touched it and the code went out. Let off it and it came back.

You have two e-mails, with PDFs, (regular e-mail address) that should be quite helpful.

Plz post back how it goes..
