Hi there,

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Good Luck!!

Thanks

A scan tool is necessary to check the TPS voltage so if tool not available have a local shop or dealer perform this. Otherwise a check engine light may be induced from the mis-adjusted TPS sensor. There is the old school way to check and your going to need a multi meter. Disconnect the wire harness from the TPS and use the multi meter to test the resistance on the TPS, as you turn the throttle up the resistance should go up as a contain value in a smooth readings without any jumps. Good luck and hope this helps, keep me posted be glad to help and why do you think there is a TPS malfunction? 

yes but u will need to adjust the setting.

it is located on the side of the trottle body on the intake manifold

is your truck gas or diesel?

nope no fuel to engine it will just turn,

Most likely TPS (throttle position sensor) D you have any check engine codes or is your check engine light on? If so I would have codes read from part store. They usually do it for free

Frank, look under your hood for a "catalyst" sticker. It should have your spark plug gap listed on that sticker along with the size of your motor, etc. Some of the newer vehicles aren't listing it there anymore, but it should also be listed in your owners manual in your glove box - if you still have it. Check the alphabetic index in the back for spark plug gap and if it's not there, check specifications.

open hood and on the very top of head lamp housing there are two L shaped rods that push down to hold lamp assembly in turn rods ad remove,Lamp assembly pulls out and headlight can be accessed.

on the handle there is a clip holding the rod one each side could have come off. or the hole where it goes is broke. u can get aftermarket any parts store

it is probably the plastick clip on the tailgate rod.. it probably fell off... i had to take the tailgate apart and replace the clip on mine.. but if your lucky you can pull the cover off right by the handle,, look inside and fish the rod up and replace clip

HAS TWO KNOCK SENSORS they are both under intake in valley of engine. remove intake and will see two black grommets they are under those best to replace both at same time

look under the latch and see if you see a metal rod. if you do, pull the rod and it should open.

i have wired alot of trailers before. and most of the time i find there is a ground problem.instead of using trailer frame for the ground.i allways run a ground wire and that has allways solved the problem.

make sure the battery wire from the starter isnt tuching the s wire on the silanoid and have the battery check

yep the switch is bad replace it.

look on the left of dash for the switch you turn your interior lights on turn it see if your dash light will brighten.turn up enough brighten dash lights. dont turn until it stop or your interior light will stay on.
