Auto 4.0L 120 series, lurchy on startup but smoothens out after a minute

Hey guys, new to this page and new to the prado world!

My car is a 120 4.0L, runs like a dream but has an issue (if it is one?) where on startup its a little bit shaky but after a minute on idol it smoothens out. If I don't wait until then its a bit lurchy like the revs are too low or something but then its all good very soon. Not sure if its a auto clutch issue or a trans oil problem.

Needs a service anyway but would love some advice!

Cheers crew.

Something simple like failing spark plug or coil??

You need to figure if its a transmission problem or an engine problem. A mechanic should quickly be able to diagnose this. Or it may be the old issue where the 4.0 runs like an absolute turd but settles after a while. next time it happens, shut it down count to 10 and restart it. It usually disappears.. Could be injectors or fuel filters if so.

Ask them to change plugs and filters on next service and run a bottle of injector cleaner thru it.

Otherwise if you are talking about a shudder crappy take off, then it may be the trans, have a trans specialist do a service on it, flush all fluids and change filter. Made mine completely different to drive after 200,000 kms.

thanks mate! yeah im taking her in for my first service after owning it (275Km) so hopefully that should fix it! basically it only happens on cold startup, warm starts are completely fine.
