glad to be here.. It seems my dads car has abit of a problem. i'll keep it sweet and simple..
car has 107k, intake gaskets have been replaced aswell as plugs, thermastat,wires,ect within the last 1,000 miles..

heres the problem..

i was taking it to my friend to have the a/c charged cuase i lost my hose/filler..half way there (40 min) it started to jerk between 10-15mph (1st gear)..Then it started jerking really hard when i put it in drive..reverse isnt as bad but noticable..all the rest of the gears have a very slight jerk...no slipping and the fluid is at the proper level.

at the same time this issue started i got a cel p0113 , p1111 and a p1189 wich is the iat sensor and from what i've researched it could be a bad connector (pin).... the engine oil sensor (p1189) is a diff story and dont think that matters in reguards to the trans.. any help???
