I installed a tv-3 auto tuner and I'm running into problems.

It wouldnt start at first. I rechecked all the connections and it started. I took it around the block and it seemed fine.
I parked it and shut it down. I started it to take it inside and I had no throttle. I checked all the connections and they all look good. The check engine light is on and the code is p0120.

The tv-3 blinks when I shut it off bit not when key on, intermittently.
Sometimes the green light is on but the engine light is on and u have no throttle. Sometimes it neve blinks red and never goes green.

It sounds like power and throttle at the air intake but all connections are fine.

Any idea's

 

Never heard of a tv-3. The code you're getting looks to be a throttle position sensor code.

 

I screwed up the data link connection. Once I fixed that everything seems to run fine.
