Good Evening, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Land Cruiser. I know how frustrating it can be to deal with intermittent engine issues. Now suspecting the leads and plugs is a great place to start. With the issue being dependent on heat i am leaning to an engine speed sensor acting up. These typically act up when temperatures go up and add electrical resistance. In order to narrow it down a diagnostic tool is needed to monitor the output of the sensor and verify that it does not have an inconsistent signal when hot. I would also recommend we go ahead and verify that our intake tract has no restrictions or that the throttle has no signs of being dirty or blocked up.

I have checked the hose from the throttle body/ measuring on the [air filter](/topics-air-filter-toyota/) to the manifold as I once had that fail and was characterized by this when placed into reverse. I have changed the air filter too.

Thanks I'll go through the major service items then and I consider my options. Seems that I'll just need to eliminate in order much like I do with my as built engines for my lotus.

I have a landcruiser 1994. Auto some times esp on hot days the car will stop being responsive and well behaved to wanting to stall or even the [engine](/topics-engine-toyota/) stop at lower revs. It seems like a mis fire when it's idling but after the car is cool it's good again. It will begin to happen after about 2hrs of driving if it's not esp hot day. Mechanic's Assistant: How many miles are on the car?
