SOURCE: Daewoo Lanos 2001 . Rpm drop when try to

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.

Is there a way you can Clarify your Question? There is a lot of words that are not meaning anything.. Is 2-3 RPM an accurate comment or are you meaning 2,000 - 3,000 RPM ?

I have a 2001 Ford Focus ZX3 with a 2.0L. I put a new timing belt on and the motor runs fine, but when you accelerate, the RPM stays wherever you run it to for 2-3 min. then goes back to normal RPM. I also...

you have a bad sending unit. I am not 100% sure where it is located on your particular engine. HOwever, I am sure that is the problem. My in-laws buick did the same thing and that fixed it.

2001 v6 escape rough idle when cold

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).

The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.

My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.
