0 big Daddy Posted February 28, 2008 Share Posted February 28, 2008 Better get a tune up done. I had a FORD 2000 model and i used to have the RPM fluctuate problem. I got all the injectors clean and replaced Air Filters etc: Then the problem was not there again.. Better get the coil replced as well. Then you can iliminate it out from the problem... I don't think you have to replce the fuel filter... /bigDaddy Quote Link to comment Share on other sites More sharing options...
0 maithri Posted February 28, 2008 Share Posted February 28, 2008 If this has the Ford/Mazda engine I think they have a shared dry coil. These are prone to failure if the ignition system is overloaded-i.e. incorrect plugs, gaps even old age! Replace the coil ASAP along with plugs as well making sure the gap is right. These do suffer from fluctuating idle problems, mostly caused by contaminated throttle body, You may find a label asking you not to clean it, ignore and clean with a good quality air intake cleaner-I use W**th. Re fit and take it for a good drive to allow the ecu to re learn it's settings.DO NOT ADJUST THE THROTTLE STOP AS THIS WILL CAUSE MAJOR PROBLEMS> Maithri Quote Link to comment Share on other sites More sharing options...

You can call them on 449797, ask for the Bosch division and get an appointment. or drop me a mail to <colombo.2000@hotmail.com> Quote Link to comment Share on other sites More sharing options...
0 ThunderBolt Posted March 5, 2008 Author Share Posted March 5, 2008 Hi all I would like to thanks all for helping. Is there any drawbacks driving with his issue. coz i think replacing coils r bit expensive and DPMC told me to wait until it gets worst. this is the only issue i'm having @ the moment .
