2L-TE lurching/bucking

[longbeach]

Hi guys (and girls). New member from New Zealand with a frustrating 2L-TE in a Landcruiser Prado (1990). Engine idles and runs well generally but lurchs and bucks when cruising around 50kph.Particuarly bad in low range with extra torque applied and impossible to drive off road satisfactorily.All sensors have been checked and a new clutch fitted. Throttle position sensor replaced and fuel line checked for air.Some help to point me in the right direction appreciated.

Could Be A Number Of Things From Fuel To Engine Mounts Etc Etc.
Has A Garage Looked At It?

Any More Info?

2LTE lurching

Vehicle has been at diesel specialist for a week and auto electrician for circuit checks.Clear fuel line inserted and no sign of air in line.Diesel specialist said it didnt seem to be an injector pump issue as it would be a constant problem and not at certain rev bands.Seems that driving on rough ground makes the problem worse as if an electrical circuit is failing.ECU not showing any fault codes.Will check engine mounts and earth straps.###### frustrating and might go back to trusty FJ40.Cheers Murray.
