FC3S Trouble..
 
Hey Guys and Girls!

Im sorry this is my first post, in here, and most deffinately wont be the last!
Ive been reading and reading and reading and am really not sure about what im actually looking for.
I drive the EX Touge Heroes RS Pantera FC3S Drift spec' imported from japan in 2007, and i have owned it for about 2-3 months..

Without being on forums, i realised i had a hesitation on full throttle, and an idle at anywhere from 1.2-1.7k but put it down to wanting a remap.
about two weeks ago, with very little rotary knowledge i was driving normally about 25-30mph, and it just cut as soon as i wanted to juice just slightly to 40ish..
and then nothing, rough idle if any, and didnt want to run under any load.
i found a broken lead and thought it would be this and a dirty plug on the same.
after replacing them it really didnt want to run.
i now have 4 new leads, 4 new plugs and a L1/L2 coil..
SHE RUNS!
However, i am back to a very very rich running, bridgeport sounding, idle (but i have to rest foot on the accellerator to keep it there..
will rev to 2.5k and then only rev that far..? If i put my foot past quarter throttle it will bog down and want to die until i release.. then is ok again..
OR. it will rev freely until i let off the throttle and it will cut, with no response from the throttle anytime after to catch it..? Make your mind up car!! :scratch:
it wont drive due to the throttle issue, so i cant take it anywhere and after racking my brain constantly for the last two weeks im stuffed.

What would these symptomns point to, and how can i be on the road like.. 5 minutes ago! I miss my maizy!!

The car has had a re-build shortly before i got it so should be more than fine in that area..
I have a video of the idle if that helps!

Many thanks in advance!!

Is the TPS plugged in?

Any large vacuum leaks?

TPS is plugged in, have read about your adjustment.. if im doing it right im only getting a reading of 1.6k ohms.. thats wound right out..(anticlockwise) but wouldnt start atall..
it ran with it unplugged, again very rough.. unterstandably.

There arent any leaks that i can just hear, but im unaware of the best or first place to look..
coming from the d.v there was a blue pipe that was blocked up (resirculation i think) with a screw and again at the plastic t-piece. it was running fine as it was like that, however i have plumbed them back in just in case!

Check for a huge leak at the turbo inlet duct.

The thing about the TPS adjustment is that it must be done with the car warm to prevent the cold start cam from holding the throttle open. If you can't warm up the car, disengage the cold start cam at the back of the throttle body.

and the turbo inlet duct will be there the air filter goes to the turbo?
