2007 Dodge Durango. Idles at 1500-2000 rpm's and stays high even when in gear. I have replaced the IAC sensor and TP sensor and can't hear any leaks. What could this be??


Did you check the throttle plate to make sure it is closing completely ?
The tps only tells the computer what position the throttle plate is in.
A vac leak could be very tough to find, especially if it is a leaking intake gasket or EGR valve if equipped.

98 dodge ram 1500 the truck idles funny and spits and spudders and misses when you give it gas. if you put it in drive and give it gas it does not go anywhere it backfires out the exhaust and intake. But...


Code 1683 is for a problem with the EGR solenoid which controls the EGR valve, and code 597 is for the IAC valve not being able to keep idle speed at the correct setting.
A leaking EGR valve could cause the symptoms you describe.
I assume you looked at the cap and rotor and they are ok.

look for a vacuum leak the plastic intake manifolds crack when the engine is cold spay the intake with carb cleaner you will hear the idle raise or stumble depending on the size of the leak

I would recommend that you replace the TPS (throttle position sensor), as it will cause this issue. You might try cleaning the throttle body itself, if the butterfly is corroded, or the throttle body is dirty it can cause this as well. I had one doing the same thing, and yesterday I used a can of throttle body cleaner and it cured it.

Dodge ram 1500 engine rpms surge at freeway speed


those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk 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.
