Trying to figure out the consequences of fixing the leak in the throttlebodys. So when me and the old man built the engine he decided to clean all the black gunk from the throttlebodys, not knowing that it was the seal. So had the high idle issue. Dicked around with the PFC and the TPS and fixed the idle. Then the 4wd started to play up, engaging in reverse, things like that. Took it to ESP and the wizards there fixed the issues with by fiddling with the TPS again. 4wd works a treat. So now I’m finally at the point of fixing the seals. It was almost 12 months ago when ESP fixed the 4wd so no-one has any idea what the car will do when they are fixed. Knowing my luck the whole car will explode
