Question about 2006 Toyota Tundra

1 Answer

Cleaned the throtle body and engine idle went from around 900 to 1,500 which makes the transmission downshift funky. Re checked all connections and see none un installed.

Why is my 1994 s10 blazer idling very fast and doesn't seem to want to downshift?

First off is the check engine light on? There could be a few reasons for the fast idle. Vaccuum leak, Idle air control valve are a couple right off the top of my head. With the engine idling (as best as it will anyway) try spraying some carburetor cleaner around the base of the throttle body, any vaccuum lines connected to the manifold, and where the upper and lower intakes bolt together.

My 1990 toyota corolla idles rough. I raised the idle on the throtle body so engine wont stall. except for idle, car runs fine

Vacuume leak is very probabe, check vacuum hoses for leaks, gasket leak at intake manifold or throttle body etc. I like to use starting fluid and spray around a bit. If you spray it on a vacuum leak, your rpms will noticably go up.

What do clean the throtle body with

Hi, the throttle body can get carbon build up, resulting in a low idle, or possible check engine light. The carbon build up can be cleaned. The most effective way, is to actually remove the throttle body, and clean the throttle plate, and air flow ports, with a good spray choke cleaner. This is available at an auto parts store. Once reassembled, the low idle situation will be resolved. Good luck...Coop

1994 Ford Probe GT - Uncontrollable Revving

ok, this is simple to do but I would get the Chilton for your car so you can have pictures of what to do. You can get the chilton at the parts store, or the library. It sounds like a throtle body sensor or the throtle body itself, but could also be your air idle control sensor. go down and buy some mass air flow sensor cleaner and a BIG can of carb cleaner. First clean the mass air flow sensor neer the air filter. then remove the throtle body it is held in by 4 botls and you may need a new gasket, NO GASKET GLUE. Now take that big old can of carb cleaner and start cleaning in and out. also down into manifold. clean everything. Now put it back together, remember 4 bolts and no gasket glue. if the problem continues replace the throtle body sensor. and then the idle air intake. It will be cheaper to take it into the part store and have them put it on the computer. They can often tell you what sensor it is ahead of all this but don't let this stop you from cleaning out the throtle body, it will make your car run better and longer.

S10 has very high idle when cold and sticks to the gas when warm

you need to replace the throtle body controll sensor. Also you may want to make sure all your linkage from the pedal to the throtle body is cleaned and lubed correctly. While playing in this direct area. Your throtle body is only 4 bolts away. Why not get some carb cleaner and get to know your truck just a litle more.

If this is a carborator, then you need to turn my warmup idle down. there are 2 sets of idles on carborators. the one to warm up the engine, automatic choke or pin settings. Get a Chilton, find out which idles pin is for what. and play a litle bit.

I think you have a throtle body so I would also check the automatic air intake sensor. It could be going bad. Check your filter and make sure its clean.

hope all this helps.

Kicdown cable came loose and now won't idle also check engine lig

check our automatic idle sensor some times refered to as a air intake sensor, also your throtle body sensor, while doing these 2 things remove the 4 bolts holding your throtle body inplace carefully remove it, and clean it all out with carb cleaner. I believe between these simple steps your problem will go away. the other thing to check being that you have 100000 miles is your o2 sensors, you probably have 2 of them. You can not fix them, once they are dead they are dead, and they tipicaly last right around 100000 miles.
