My beloved Jack has been driving me crazy with erratic ilding, surging etc, Was getting ready for a divorce LOL.
Scan guage indicated maf so replaced that for $260, couple days later it is doing the same again GRRRR, stalling at lights etc.
Anyway one of the ferry drivers at work is a retired mechanic and suggested I spray all the sensors with electrical contact cleaner.
I used servisol electrical clean and lube. Removed all plugs(
well 4 that I found) and sprayed both connections and then sprayed carby cleaner down the air intake as
well. After some rough running it is now running like a dream again, and the best part the owner of the business next door to work lent me the contact cleaner. LOL
Anyhow I hope someone else can befit from my experience.
We have been running our new Nullarbor on premium fuel and after a run seems to have better pick up and fuel economy seems to be improving but still not good. Also tipped half a bottle of petrol conditioner into a tank and pumped up tyres to 40psi. Next week new air cleaner and plus 50 globes
Cheers Pete

Yes Axle the days of new plugs and pionts, and if really keen new leads and clean the carby are long gone. Actually this is the 5th efi car we have owned and the first to give any problems like this. From what I have read on other forums it is a Jack 3.5 thing, but now I understand more makes it easy to fix.
You have a 4.5efi now If I am not mistaken so could have similar problems although rare in toyotas.

Pete,
If the problem returns or persists, I think I have the answer for you.
Experienced the exact same symptoms you describe.
Tried cleaning the MAF sensor but the problem persisted.
The Dealer could not detect the cause of the problem either.
I googled the problem and found reference from a Isuzu Master Machanic to a possible leaking Inlet Manifold Gasket which is a common known problem with the V6 Jack.
After removing the top plastic cover from the manifold on top of the V6 engine, spray around the edge with some brake clean.
If you observe bubbles, one of the manifold gaskets (top or bottom) is leaking.
If I find the site again, I'll attach the reference.
Bill

Sand man you are on the money, but I replaced the3 inlet manifold gasket about 6 months ago. , but it may have gone again.
Thank you, do you still have your Jack?
Will give it a couple of days and monitor how it is going
Cheers Pete
