Gutless GU 4.8????

[glennb]

Gday all

Its been a while since ive been on here.

Just brought myself another Patrol with More issues than the last one.
I got over trying to repair the last one so i thought i would buy a later GU 03 4.8
it seems to have no power and very jerky in 3rd.(bunny hops)

Ive changed the fuel filter air filter and put a new pump in and still no good.

Any ideas before i give up and buy a toyota?

Where are you located?
O2 exhaust sensor, maf sensor can cause power loss if they're faulty

X 2 clean any sensors and /or check all your vacuum hoses

Have you checked for fault codes?

Have you checked for fault codes?

is there a way you can do this without spending millions on a machine
IE computer leds?

ive checked the temp sensor for the ecu ive heard that these can cause issues. trying to find out what resistance they are meant to be.
Mine is 11ohms cold 11.8 ohms hot.

Have you thought of taking it to a Mechanic ????

I have just read my workshop manual on your motor ,
and could find no reference to those values you posted

^^^ what Bob said.
I'm by no means anything close to an expert on these things but the 4.8 is normally a very reliable donk. I'll assume it is an auto and say that I can't see how a bung engine is going to create a "bunny hop" in a specific gear, especially with the auto.
I would be thinking driveline somewhere. Is it only 3rd that this happens? Does it happen in 4WD, or 2WD only? How long has it been happening? Any other circumstances you can think of?
