Throttle And Idle Problem

[YPURV4]

Hey people in the last month or so I have been having some wired things happening when starting my car.

First is, when I start my car and put it into drive the throttle indercator light comes on and the car starts running like crap (blup blup blup) then I switch the car off and start it again and its fine? (this has happend 5 times in the last 2 months)

Second is, also some morning's when I start the car it will idle at 1000 rpm and the car feels like it going to take off by its self.It's a bitch trying to get out of my drive way because it just wonts to take off even with my foot on the brake( lightly).

But after a bit it drops down to about 600 rpm, it is really starting to trip me out, apart from that the car drives fine.Both problems are only accuring on starting the car.I have a XEDE piggyback and im wondering if that's apart of the problem?

Oh yeah and it stall's every now and then aswell.(not that often but it has happend)

Would a EDIT fix this problem?

I went to ford and they said no fault has been registered, which is bull crap

Any help idea's would be appreciated.

Cheers Michael

Clean throtle body first off

My t will also idle realy high when first started of a morning. It'll gwt up to around 1200rpm.. When you initialy start your car you will also see the instant litres per hour hover around 5.1 +-. I generally start to drive my T when it goea down to about 3 litres per hour. This change also will allow enough time for your revs to drop to around 800 - 900 rpm

In other words.. Let your car warm up before you start to drive it

Mate pull it right down..

A good product to use is carby cleaner

And when you put it back together make sure you double check all your hose clams.. Wouldnt want to loose boost now would you

This used to happen to me when I had an RDP computer. After getting edit the problem never occurred any further. Maybe it's a quirk of piggybacks ??

Second is, also some morning's when I start the car it will idle at 1000 rpm and the car feels like it going to take off by its self.It's a bitch trying to get out of my drive way because it just wonts to take off even with my foot on the brake( lightly).

Normal, high RPM at start up to warm up cat.

But after a bit it drops down to about 600 rpm, it is really starting to trip me out, apart from that the car drives fine.Both problems are only accuring on starting the car.I have a XEDE piggyback and im wondering if that's apart of the problem?

Thanks Rob & Robin , I did suspect the piggyback had some thing to do with it.

And to the FATS your a real funny bugger arnt you

This is the throttle body I have been running rdp system for 2 years and it has not caused any idle issues to do with the throttle body.

If you really knew how they were set up you would know the rdp and any other piggy back computor does not have any control of the throttle body.

PS I might add that this also happens with edited cars.

My car is edited and I occasionally have TPS issues too. Strangely enough, it seems very much to coincide with whether my car is warm(ish) or cold. If I start the car and I'm in a hurry to get away and I put it into reverse while it's still idling quite high, I will quite often have the TPS light come on and have those idling issues (resolved, as you said, by restarting the car). But if I let it warm up for a while and the revs drop, then I rarely have TPS issues. Go figure.
