I have a Madza Precidia Mx3
My car had problems starting one cold morning and I brought it to a mechanics. After changing the basics; spark plugs, recharged the battery etc.. the car started. Then he told me that my car idle was low, so he boosted the rev higher. He turned the adjustment screw on the throttle body. I left that day the car was running. I noticed that when I started the car again that my tachometer gauge was on 2 (since then I had trouble starting it to begin with). I brought it again to another mechanic and requested that he brings it back to normal. I tried to drive the car the following morning and now it seems to be too low. It stalls easily and won't stay running unless I pump the gas and even backfires while driving. It bascially not safe to drive. The funny thing with this is that I saw him adjust it and at that time the gauge was showing between 0 and 1. Any ideas on what the problem is or the procedure to adjust it correctly.
Thanks.
Idle Problem
Before adjusting the idle you need to put a jumper between TEN and ground inside the diagnostics box. You can just use a paper clip for this.
Make sure the car is at normal running temperature, in neutral (or park) and turn off all electrical loads like headlights too.
If you don't do this the ECU will try to compensate for the adjustment you are making and you'll never get it right.
Kristy - you can do this yourself so long as you know which screw to adjust on the throttle body. Adjust it to about 700 rpm.

Any pics or step-by-step instructions...? Where is this box at...? If I already messed with it (the idle screw), do I need to do anything specific...?Grants wrote:...Before adjusting the idle you need to put a jumper between TEN and ground inside the diagnostics box...
When this thing hits 88mph, you're gonna see some serious TIHS...!
