Dodgy engine running, help!

[dan-hipgrave]

Hi, i used some of the powerboost spray on my engine earlier to decoke it, but when driving it now it needs the choke fully out constantly or it will stall and will also stall if the revs get low - even with the choke out. The engine is also really lumpy now and the car kangaroos down the road all the time. What could be causing this? any help is greatly appreciated

im guessing its screwed 1 of your gaskets and now u have an air leak!! otherwise its loosended up some crap which is now blocking something

Try some Carb/Injector cleaner in your petrol? It's pretty good at dissolving gunge. (it's even cleaned my paint up nice where I spilled some once!)

sounds like you have cleaned all the coke off the valve seats which was once sealing them. the only remedy is to take the head off and re lapp the valves in or just put up with it untill the coke fills the holes in again. could take a while tho

Cheers for the replies guys, could it be that getting the carbs re-tuned would solve the problem?
