My 3.5 efi did this once upon a time after high speeds or fast acceleration would stall on deceleration; pulling through all the vacuum/ventilation pipes to clear any blockages sorted it.

I have 3.5 efi in my 90 with ZF 4 speed auto. wiring loom is defender at the dash through the bulkhead and then just the relavant ecu loom and efi electrics spliced in at this point. rest of the loom as all defender. my ecu is mounted behind passenger seat along with the additional relays for...

Did the Sahara and this is what i used, mainly because the champion plugs overheated and killed the ignition, make sure you fit NGK. also suggest if you have kenlowe ditch it as mechanical fan spares you'll get out there easily but replacement electric probably not. Coil, HT Leads, Plugs, ecu...

I'm no expert but did a little research on this for my 3.5 efi 90. The fuel pressure regulator should hold pressure in the fuel rail about 36psi so as long as your pump can deliver more than that then should be ok. I think I recall most post recommending using pump from 2l cavalier or xr2 pump...

Are the cap leads and rotor original dealer kit? lead genuine land rover, cap is the blue one that came with remanufactured dissy from RPI Does it have e massive amp under the coil? No has small amp on side of dissy Is the vac unit working on the dissy? yep Have you done a...

At the moment i have the whole dashboard out so trace thed wiring and confirmed connections to correct senders. Crimped new connector along the way.Oil light comes on with ignition and goes out when running. Did a 30 mile trip today. hot tickover is about 25 , cruising is about 50 and never...

Taking the dashboard out of a ninety is not a 5 minute job! Finally got to my wiring loom and after multiple cable colour changes traced it through the bulk head to a black box that turns out to be a thermo control unit for a kenlowe copy electric fan - needless to say don't have a heated rear...

Tried tracking down my non existant heated rear windscreen warning light last night as its still coming on after 10mins of driving and i need to find out what is connected to the other end - dashboard now in bits!! (that's no easy task) New problem - found loose connection on oil pressure...

OK next question, if this is a solenoid operated air valve for air con and its in a 90 with no air-con and not connected does that have any effect? should it be removed and bypassed or blanked off?

bit more detail. its under the intake to plenum along the fuel rail, that's the thottle sensor to the right. its on a 3.5 efi flapper (4CU ecu) but i think it could some form of air solenoid valve or something from the hotwire (14CU/X ecu), hence not plugged in.

the cylindrical thing in the centre of the photo. the black lead coming of it is the unplugged connector in the foreground.

Cheers Joe, going to Billing on saturday so will see if i can pick up some of these tools there, if not ebay next week! Just picked up some recon heads as they were a bargain and a friends diagnosis was that due to the amount of crud in the rocker covers that mine are probably history anyway...

fair point - maybe should delete 'never' and edit my advice to "If you don't want to bite off more than you can chew only buy a hybrid if its build is fully documented and your buying from somebody with first hand experience of the vehicle who is prepared to walk & talk you through it".

Hi All, Just signed up yesterday and have a thread posted on some V8 probs but thought I'd add a hello hear also and share my first piece of advice with all..... Never buy a hybrid build your own.. otherwise you'll probably end up with something like mine, a Ninety with a RRC engine and box...

just got an adjustable fse one from rpi, took under an hour to fit and most of the hard work was drilling holes for the mounting bracket in the bulk head and then try to get the supplied screws to turn through the steel work (thread to tight on screws for thickness of steel on bulkhead). if you...

having similar issues with a 3.5 efi as you describe. did you get a resolution to your issues?

Hi Thanks for the reply. engine has never overheated when i've had it, even in morocco at 40 degrees. the engine was changed before i went for 60,000 miler as a precaution as i wasn't sure about the original as i didn't do the conversion and the local LR guys (Foleys) said it was a good known...

Hi, New to the site and looking to see if anyone can offer some advice. Have a 3.5 efi (flapper) with 4 speed auto box from 1988 RR classic in 1986 Ninety. Was running great but went a bit rough last year so had a bit of an overhaul, new dizzy, HT leads, plugs etc - was hunting badly so all...
