Two things you can do ; add sea foam as per directions on bottle too your fuel system; 2 Get spray engine cleaner from your local parts store, grab an old tooth brush and remove the rubber tube were it enters your engine. manually open your throttle plate with a screwdriver (carfully it opens in one direction only.) spray a little amount of cleaner in the throwt scrub with tooth brush, wipe clean and repeat until all the garbage is off of the plate and throttle bore. leave no trace off cleaner or it will cause th throttle blade to stick. then replace all removed equipment start it up and rev. it a couple times to clear cleaner out of engine, then go dog it a couple times on the hwy. this is an approved method from GM. it really works just ask around to other GM owners. One other thing if it startes and stalls after this, you must relearn idle by starting let stall, turn key off wait ten seconds and start it again. repeate until it idles properly.

2003 gmc envoy xl 4wd 5.3 litre idles low and stalls mainly when parking but sometimes also when coming to a stop...have replaced many parts already.


Hello: Get some carburetor cleaner, remove rubber tube going to the throttle body. Spray cleaner on rag and open throttle plate and clean all black stuff (carbon) off the throttle plate and the inner bore of the throttle plate. Make sure its clean, You can spray some in the throttle body but not very much as too much and you cab blow the engine up. If build up is bad (carbon) go to Auto Zone and purchase a small brass bristle brush to help remove carbon.

my f150 4.6 stugles to stay on after i start it however if i keep my foot on the throtle long enough the engine comes alive with no knocking or smoke but when i remove my foot off it chockes with very low rpm and it shuts off. i was told that the engine is out of timing or need to replace timing chain???


you might try cleaning the throttle body first. Buy some good Throttle body cleaner and a old tooth brush take off the air intake hose to the engine, have a friend hold the gas pedal to the floor with the engine off and spray and scrub the throttle body good replace the tube crank it up and rev it up a little to clear out the cleaner this may fix your problem

cleaning throttle plate and MAF sonsor


TO clean the throtle plate use a small tooth brush and some throtle body cleaner. remove the intake hose, spray the throtlebody and then open the throtle plate and spray plate , use brush to clean body and plate then spray clean try not to spray to much into engine , after its clean then start the engine you may have to hold gas pedal down to start as it going to be a little load up with fuel from the cleaner, some time sit will start up on its on and run a little rough for a few seconds and clear up. As far as the mass sensor this needs to be cleaned with mass air flow cleaner, this is a spray like the throtle spray but is made for that sensor and drys fast, spray the two sensors inside but dont touch them or move them spray as close to them as you can to clean them, good luck.
