help please stalling
Well i just bought a 99 26' donzi with a 502 and a m3 procharger on it. It starts fine but surges really bad like 900 to 1500 but it stays running. When i put it in gear it stalls out, if i try to give it gas, or if i let it idle in gear its will stall out after about 15 seconds. I am going to change plugs tomorrow and see if that works. Does anyone have any other ideas. Also there is a beeping like every 5 seconds. All fluids are good and full and guages are all where they need to be.

Ya it ran good when i tested it. Im gonna do a scan on it tomorrow and see what comes back. It might be the iac valve. It surges really bad. Runs in neutral soon as i put it in gear and give it gas it stalls out.

So i changed all the plugs today and it didnt fix it. So i made one one those home made led code scanners and it can back as my tps code. I went to take it off to replace it and could not find the wire harness that it plugs into. I then realized there should be wires going to it. After searching i found a unplugged wire, what do you know it goes to tps. Boat is running great other then i spit a belt off i can handle that one. Thanks every body for your input.
