idleing issues and sticky throttle
I recently had a water leak on the main water rail from the water pump to the heater hoses so I had to take off the upper manifold to get it fixed. Ever since I have replaced the manifold again the engine idles funny on gas or petrol. On petrol after you give it a rev it hovers around 1200 for a few seconds and then VERY slowly comes down to about 700rpm. But on gas it will idle at about 200rpm or lower! It will sometimes stall if I am doing a u-turn or even pulling up at an intersection.
Also my throttle seems to be getting stuck off. when I let go of the accel. pedal and then put my foot on the pedal it gets stuck. It seems 2 be something to do witht he throttle body cos it does it if I use my hand on the mechanism on the throttle body as well. Tried to spray cable and surrounding areas with WD40 but didnt help.
does anyone know what's wrong or know of a good mechanic/gas specialist in the northern suburbs of melb? I want to get the gas system check anyway.
