Question about 1992 Plymouth Grand Voyager

1 Answer

Running rough While driving down the road it will start to run like its losing power but if I push the gas pedal down a little more it pops a few times then runs good for a sec. I have taken the breather hose off the throttle body while running rough it sounds like its getting to much air. There is a hole inside of throttle body right where the throttle opens that is some kind of vaccum thats where I hear too much air. The van runs good most of the time but you know how that goes please help thanks.

could be the idle air control solenoid , its right below the throttle position sensor(opposite where you can open the throttle with your hand) on the 3.3v6, when that goes it does all sorts of stuff, bottom line its going to have to be put on a dyno to see what it is but you can take that part off and get one at the junkyard we got a whole throttle body for 10.00. Try also to disconnect the electrical connector off the idle air control solenoid and see if runs any differently, then youll know right away

Daewoo Lanos 2001 . Rpm drop when try to accelerate when push on gas pedal. Also rough engine running when try accelerate and push on gas pedal

inline or in tank fuel filter (replace).. fuel pump or injector worn out..
need tuneup (plugs) rough engine.. not firing on all cylindars.
exhaust clogged up can do same thing.. go have catalytic converter checked (they drill tiny hole and pressure test it) .. if bad replace.. replace muffler if need.. a bad converter will not allow whole system to breath and you lose power and get same exact symptoms. you can hook it up to a diagnostic machine at autozones for free.. they plug a computer into your car under dash and it runs all the CODES for things not running right.. codes stored in your cars computer for future repair needs.. when car runs bad like it is for you.. it generates codes for things to CHECK and look for to maybe replace. You will get all the things plus a few little sensors that are cheap and easy to replace too.. start with autozone and computer codes.. they will go in store and print little papers for you..then start on cheapest suggestions.. little sensors and slap some plugs into it.. you tube how to if you dont know and find step by step videos for your make model car.. you will have to go to a shop to get a new converter welded on and it is a little high priced.. but you HAVE to have it.. if its broken.. you have to replace it. Dont let people tell you to cut it out and just put straight pipe as it will affect other things running adversly and cause you more problems.. the cars are set up to run WITH them on. I have had this problem and it was my converter.. but it needed new plugs and I gave it a sensor by the fuel injector.. it runs excellent now.. good luck! I dont know where you are.. but if there is a garage that can run the codes for you ... thats where to start.

Probably a crank angle sensor, maybe a throttle position sensor, but those usually throw codes out. Could just be a bad computer, too.

It sounds like the idle speed actuator is part of the issue. I would also have the exaust inspected for a blocked catalytic converter.
