Rough idle warm up or cold

87 22r in X-tra cab 4x4: Idle is rough cold or warmed up. Recent valve job, ect. Carb has been gone through and tech. said something in carb was worn and causing problem. Come out of idle circuit, runs smooth. Tech. said good option is to change carb out for a Weber set-up for this application. I know cost of this is cheaper than a new OEM carb. Is this a good option, or is the original carb. worth keeping. If so, what in the carb. is causing this problem and is it fixable? Thanks in advance, Brant.

The carb may be able to be rebuilt but those old *** carbs where not very good to start with. The Weber application is a great one and will last a very long time you can also get a kit for a holley if you want to get more performance. The engine in your truck will last forever as you already know but it will start leaking oil on the front side of the engine. When this happens the tech will try to replace the pan gasket but the problem will be the front main seal. When this happens have the tech change the timing chain at same time and you will save a fortune.

check that the EGR valve is not sticking or has a vacuum leak. This valve will not operate until the engine is warm.

check also the engine coolant temp sensor (ECT). This sensor tells the engine computer that the engine has warmed up, so if it is faulty, it could be sending wrong information to the computer. If the sensor is disconnected, wires to it broken, or faulty in full cold mode, it will tell the computer that the engine is very cold, like -40F. The computer will schedule fuel for cold conditions. This is usually way too much fuel for a warm engine and it will rich misfire, idle rough, and be difficult to start warm.

The ECT has two wires going to it and is dedicated to sending information to the engine computer. It has nothing to do with your dash gauge that shows coolant temp. That sender has only one wire and is dedicated to the coolant temp gauge.
