ok im making a new thread to clear my problem up

my cars been doing all sorts of things

i have changed my idle control valve and the car dosent stall or rev up on its own

but my idle hunting, slight misfire, hestation and sticking on revs dropping, and crackley noise afta 1500rpm is still there!

i changed my coolant position sensor and my map sensor and no change

i now suspect its the throttle position sensor, ive read up on this and most the symptoms it says caused by a faulty tps is EVERYTHING that my car is doing. also.. when i unpluged the map sensor.. it idled ok n changed... i unpluged the temp sensor and the fan cut in... i unplug the tps and thers no change.. car druns EXACTLY the same with it pluged in as without.. which makes me also think its not working or not working correctly.

do you agree that this is probably the problem??? before i go spending alot more money on my saxo oo btw its a 1.1 mpi

well iv now taken off the tps and dne the tests.. used the voltometer and when you turn the throttle the reading should increase/decrease smoothyly and mine does nothing voltage dosent change so i think that this should deffinatly solve my problem... touch wood
