OK I cleaned the MAF sensor cleaned the throttle body, still same issue,

also need help with high revs and the start issue with petrol no comming through however when she does start and I drive no issue but no power, and when I get to a robot and stop she revs high.

need help anyone.

thanks
Miller,

What's the engine code? We might have had the same engine in a different platform, or you might have the older SR engine.

1.6 16v cars have no MAF, but do have a MAP, located on the side of the intake manifold, behind the dipstick, so you assumingly do not have a MAP sensor if it has got a MAF sensor.

Codes can be found with a fault code reader that plugs into the OBD2 port, located under the AC/Fan controls, behind a cover.

Check all your vacuum hoses - all the pipes connecting to the intake manifold. Brake booster hose is common to crack and fail, as are all the breather hoses.

What does your temperature gauge read when the car has just been started from cold?

these AKL engines are known to act up like this when the temperature sensor is faulty... and with you saying it goes really hot on short trips not on long ones i would deffo change the temperature sensor first and see if it makes a difference... i would also check the vacuum lines and the brake servo pipe for leaks... if that all seems to be ok, than i would replace the spark plugs and clean the throttle body... as those all can cause the car to jerk... and if you have no access to a code reader... make sure the in-tank lift pump works and replace the fuel filter, also make sure you've checked the spark plug cables aren't broken and if you do all this you eliminate everything that can be a problem....

PS check if the radiator fan blows once the engine is at operating temperature ( 30 min at idle should be enough)... if it doesn't come on, than you know why it gets hot when you do short trips but stays cold on long ones. that can be related to the temperature sensor but could also be a stuck thermostat.
