If it will idle and not bog out and die, let it do that for a while. Something probably is still wet and needs to be dried out. IF the engine can get up to operating temperature and stay there for a bit it'll dry itself. IF you've already done that and everything is dry, you might have done something bad. I'm sorry, I can't even begin to guess what exactly. I've never washed my engine :/Wrd_32 wrote:I recently decided to clean my engine so I sprayed some simple green over the whole engine bay and then rinsed it down with water.. Nothing to extreme just normal pressure water.. My question is what should I check or dry out to make my engine run better? At the moment it shakes heavily and wont even get up to any speed.
