Hi Jeff, I'm glad to help! Jeff, with the engine running tap on the throttle position sensor, If it revs-up when you tap on it then replace it. Hope this helps and have an awesome day Jeff.

2004 dodge neon, when ya start it, it revs up and imedietly red lines, it wont calm down unless i throw it in neutral, thats parked, now if i push down on the brake real hard and put it in gear it goes...


Hi and welcome to FixYa!

Few things that can cause this issue. You may have a faulty TPS (throttle position sensor) or a bad MAF (mass air flow) sensor. If the TPS is bad you can experience irregularities on acceleration. If that's the case the TPS should be replaced.

If the MAF is faulty, there will surely be irregularities on vacuum supply which result to erratic idle, one good reason why the rpm hits red line during start up. I strongly suggest that you have the two checked and replaced if necessary.

Hope this helps and thank you for using FixYa! Have a good one!

Replaced water pump and timing belt on my '95 Plymouth Neon with 154,000 miles. Starts right up (warm or cold) but has a very lumpy idle and dies when I stop at a traffic light. It starts right away...


Welcome to Fixya

You might need to have a good tune-up with your car. Did you notice the needle of the RPM going up and down? The normal idle RPM is 600 to 800.

Thank you for using Fixya!

If it revs up and down you need retrain the car to idle. I know it sounds crazy but you need to ask dealer or local shop the steps to do it.

Cold days 94 f-150 high rpm start


probably is a emissions sensor problem, lots of these parts are plastic. check out the throttle cables, lub em wd40. there is a type of valve somewhere on top of engine, it may be cracked, pcv valve stuck. lots of possibilities, almost too much for solution online. something emmissions with an electronic sensor is acting up.

In park rpm goes from 1100 to 2000


Hondas will have a surging idle when way low on coolant. Maybe this is the whole problem. Check the heater hoses for a hole. (passenger side rear of engine.)
