Replace Idle control valve . You might try taking it out and cleaning it with carburator cleaner this sometimes works but is only a temporary fix .

What would cause a 2003 dodge ram engine to rev up while driving. It woll also stall Iif you put it in gear and mot push down on the gas


OK, I know I hear loads about the rev limiter, and having replaced only to have to spend more on tune ups, filters, breathers, etc, etc only to find that the problem is still there and that there were other simple typical problems overlooked that could be causing these symptoms. So you should know that these "other" things could be causing a variety of other "non" issues, some as simple as the distributor cap working it's way loose. Check that (as well as the spark plug wires) and make sure they are firmly seated and the cap is locked down tight (This has resolved this problem the last three times I've been asked to look into this). Second, these same issues are what you should expect from a dirty throttle bottle, remove the large air hose and clean the inside of the throttle body, making sure there is no gummy varnish holding the butterfly gates opened or closed. I like to use baby wipes as they contain no harmful chemicals and contaminants, one or two usually allow you to wipe the entire surface area clean. If after doing these things, the problem still exists, I would investigate replacing the IAC (Idle Air Control) valve. these are very simple and affordable things you should do to fix the problem, with no need to go much further.

Sat. 01 sl wait 1/2 hour to start when warm. stalls when ideling 1/2 hr restart


You have a bad air intake manifold gasket. If it runs idling high, take a can of brake cleaner and spray it on the air intake manifold by the firewall. Spray it right where the air intake bolts on. There are 8 10mm bolts or nuts there. When you spray it while idling, the revs will come down. This makes sure that is the problem before you go any farther. My 02 did the same thing.If you need to know how to change it, let me know, I can walk you through it. It's a one to two hour job, b ut easy

Car is cutting out when stopping or slowing down, revs are goin down


1 Check for vacuum leaks, 2 Check the EGR valve, on mine the large nut on the metal pipe had come loose. 3 Clean and re-gap (or replace) spark plugs seemed to help. Mine (2004) needed new EGR valve to fix.

01 Yukon Transmission Problem Come and Goes Without warning my transmission stopped working. I drove a few miles to the gas station without any problems. After filling up, I went to drive away and it...


Take it to a reputable trans shop. These transmissions are controlled by a computer. If this is a 2500 or 3500 Yukon, I bet it is equipped with the 4L80E transmission. These have a tendency to allow transmission fluid into the large electrical connector, and it shorts out wires and can make things go crazy. There is a way to silicone the leak and fix it(videos on YouTube) or a good honest shop can do it without replacing parts.

Very uneven running


Here are a few things to check check idle speed control , TPS- throttle position sensor and also very important check for vacuum leak on intake any broken hoses or intake itself gasket leaking Very possible for this problem. A simple test is when engine is running up and down use an intake cleaner (in compressed can) and spray around intake manifold if there is a vacuum leak the engine will surge up . This could man intake gasket or vacuum leak. Good luck and thanks for using FIX YA.
