New Rangie

Collected the new Rangey at the weekend - 1991 3.9EFI Vogue (see pictures). She has a 2" lift, steering guard, diff guards, 15" steels and insa turbo remoulds, and a raised intake. I bought her as an off-roader, and am in the process of checking all the mods the previous owner has done. So far, they seem pretty good.

He reckons its a year since a full service, so I will start by putting in a filter kit, change engine, gearbox and diff oils along with a plug check and change.

She runs great, except for an irritating idle problem. Only happens when she's been standing idling for 10 minutes, not just after the engine is hot, so I am guessing its happening when she's hot under the bonnet. She idles beautifully, but then revs drop, she coughs and recovers - unless there's any extra load in which case she will conk out.

Could fitting the raised intake bugger up the EFI?

Been searching the forum and plan to do the following:
1. Check all air pipes and connections for loose joints/leaks
2. Disconnect battery and reset base idle
3. Replace coolant temperature sensor, air temperature sensor
4. Check throttle position sensor
5. Check leads and dizzy (they are both new and very clean)
6. Check all connector plugs for cracks/corrosion/wear
7. Panic

Any thoughts very welcome...

now that is nice

clean the stepper motor. carb cleaner should do the trick or mister muscle oven cleaner if its really bad.

Did you get this off Flea-Bay???......... I looked & nearly took a punt at (Either this or one very similar)

If it is the Flea-Bay one his description came across as very knowledgable & knew what he was doing


Looks VERY nice!!!!

Love the name of the pics by the way "Christine"................... just make sure the speedo don't go backwards!!!!

Nice looking motor. Try removeing the snorkel from teh front of air filter box and see if it still does it. Always go with a cheap option first lol

Thanks for the tip, obvious really.

Got her warmed up today with a blast up the road to gas-up and then pop into B&Q. She wouldn't repeat the bad idle, but when I opened the hood there was coolant ****ing out the filler cap.

I hope I just didn't put it back on properly... Will check out once she's cooled down.

Ok, gave her a good warm-up today. Started her up, she coughed and died. So I detached the intake at the filter inlet and went for a drive. When she was properly warmed up went hom. Idled no problem at all. Then I reconnected the intake and there was still no problem! So don't know if the intake's the problem or if it's just intermittent.
