I've fallen in love with my 89 Max, I never knew how much I missed a 5 speed. Picked it up with 112K miles, and it has been simply flawless. This is the problem - it's not perfect anymore . When warm, the car idles perfectly at 750RPM. About every 10 seconds, it will drop to 700 or so. You almost cannot even see it on the tach, but you can feel it.

Any ideas as to where to begin to look? I suppose I could just ignore it.....

 

numerous, numerous, things can cause that. everythnig from the TPS, MAF, injectors, coil, filters, just check them all and verify that they all are fine. air and fuel filter, throttle position sensor, mass air flow meter, injectors, coil, then let us know if all checks out ok. if it does then that narrows down the obvious.

 

It's a VG my moneys on injector

 

boo on you okay, lots to check out, and so little free time... I'll keep an eye on it. I need to get some other cars with far more serious issues fixed....

thanks

 

we love our VG injectors....not!
