Hey everyone I've been messing with this problem for a year now and I can not get it figured out. The car is an 89 mazda mx6 gt atx. Here are the symptoms, shakes at idle in drive around 700rpm, 90% of the vibration goes away when I put the car in neutral. If I rev the car up about 100 rpm it helps the vibration go away also. Could be why its better in neutral. Tried adjusting the idle scew with the test connector grounded. I could lower the idle but could not raise it past the 700rpm. Another problem related or not is that it hesitates bad the first time I hit the acceleration after its been shut off. Doesnt matter how long its been shut off it does it only once and feels like the car is running out of gas for a second or two then its back to normal and accelerates fine.
Heres what I have replaced: spark plugs, wires, dist cap rotor, fuel filter, o2, air filter, two side motor mounts, timing belts.
Heres what I have checked: timing, egr, IAC, the other two motor mounts, vaccum lines.
I have read tons of previous forums about people with the same shaking at idle problem but no one really seems to answer it. O yeah the shaking has been going on for a good couple years, while the acceleration problem started a few months ago. Sorry this is so long someone please help, as they will deserve a LOT of KARMA.
Thanks
