Another rough idea problem!

Recommended Posts

Yep hose from back of plenum to fuel regulator there. Changed it to a new bit of pipe just in case there are any issues with it. New pipe is not squidgy like the one thats on there at the moment...

There's also air temperature sensor in the AFM.

it's also worth eliminating air leaks finally - can potentially be anything that connects to plenum so I'm thinking crankcase breather. brake booster or even fuel regulator. could try blankng all ports off just to elimi ate and then test- wouldn't drive without the brake booster tho! Also check stepper seats properly - no washer but thread sealant

I thought the ABS ones were hydro and earlier are vacuum?

Yeah, this one is a 1992, I'm going to assume it has ABS by then.

yep, 1992 with ABS.....I will drive it to get it warm and then see if I can blank all the hoses. There is also a vacuum supply for the now non functioning cruise, so I might disconnect that as well.....

It came with a fibre washer so it's fitted with that. Its done up quite tight so probably no air leak but the plunger probably also won't be seated properly.....
