mixture off when downshifting...87 Topaz
I think the fuel/air mixture is getting fouled up when my automatic transmission autamatically downshifts at about 32 mph. When this problem first started simply removing your foot from the gas pedal and then reapply pressure to the gas pedal fixed teh problem. Now, 5K miles after it started, you have to allow the car to slow and shift into 1st gear before the problem is fixed.
When the problem happens, the car sounds funny like it is running out of gas but does not surge the same as running out of gas. You can floor the car and maintain the same speed but you cannot speed up.
I think it could be a throttle position sensor but would like some other's ideas because money is limited.
