Hey guys, I have a rb25det S2 engine and it has had a complete engine re-build (bottom end BRAND new all parts and top end has been reconditioned but i left all the seats and valves and injectors as they were fine) has and only done 283km because its only been on the road for 1 week.

The car used to shake when i turned it on before i had the engine re-build but it is still doing it after the re-build. The engine shakes and then the car shakes from it and the RPM drops too 300 and tries too stall and will if i don't hit the accelerator to 2000 RPM after that i can turn it off and it wont do it again until i leave it for an hour. If i drive it for 15min the engine warm and wont do it again for about 12 hours.

so its a cold start problem.

Also i get a strong smell of fuel from the exhaust.

any help would be appreciated thanks.

Hey mate, try cleaning your AAC valve. I did this, as my car was doing the same thing plus was stalling at the lights when i put my clutch in. Click here for a really good DIY AAC valve cleaning guide. It only took me an hour and was really easy to follow. Hope this helps. Post up your results.

      Unpeeling the Orange

      By MBS206 · Posted

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
