Check the fuel pressure and flow. The sea foam could have cleaned up the crud in the tank and that stuff will plug filters and wreck fuel pumps. You could also check the TPS for proper operation.

How to check the TPS ? And make sure its working good ?


You need an ohm meter and the chart that shows the signal in, signal out and ground, disconnect the sensor, hook up the meter to signal in and signal out, as you slowly open the throttle watch for any fluctuations or drop outs in the readings, then move one connector to the ground and make sure that the sensor isn't shorted internally to ground on the signal in and out contacts.

I have changed the TPS , but still the same !!


When you press on the gas, vehicle start to slowly move, then it jerks and takes off. The governor pressure sensor and transducer need to be replaced. Its taking off in (limp in) mode. Then it come out of limp in and shifts normally. Ive seen a bunch of these.....

Have you had the rig checked for codes?


I was talking hypothetically, If you are responding to me, I'm trying to help as If it is governor issues it doesn't always set a code.
