Does any one have the vacuum pipe diagram for a toyota hilux 1994 1800 SR with a standard 2Y engine? When i pull the choke out the idle drops drastically and sounds like it miss fires.

When the engine is running ragged, place your hand over the opening of the carburator. If the idle smooths out, you have a vacuum leak somewhere on the intake system; it could be the base gasket for the carb, the intake manifold gasket, or a broken vacuum line, or a combination of that. What you have is too much air getting into the engine, but the air is not going thru the carb. Please check for vacuum leaks, you can use a can of carb cleaner, spray the intake manifold, if the idle smooths up, that would be a good place to start.

Make sure that your truck vaccume line goes into the intake manifold where there is a vacuume spiggot at the base of the carb. You may have iadvertantly hooked it up to the wrong place.

First, take it back and give them a chance to correct there repair abilities or lack of knowledge. Hopefully they will not want to charge you. Find a good repair facility before you need one.
