My 2001 Kia optima will not accelerate over 3000 rpm

I had that exact problem with my 2005 Kia optima.. It suddenly started one morning.. My Kia would not turn over.. I felt it was a power issue so I unattached my after market fog-lights that I have attached to my battery.. That got my ride to start, but upon driving it refused to go past 3000 rpms (in all gears)... I took apart my battery terminals and scrubbed them down with a tooth brush and coca-cola.. That was a perfect fix for my situation.. My Kia ran perfectly right after...
Good luck

Input speed sensor

The input shaft speed sensor is located on the side of the transmission by where the engine "inputs" power to the transmission (via torque converter), thus rotating the input shaft.
The output speed sensor is located by where the axles attach to the transmission, and measures the speed that the transmission "outputs" to the axles (which make the wheels turn) and that data is also used for your speedometer reading.

2002 kia optima slipping into 3rd and 2nd gear while driving

UPDATE! ! ! Fixed this problem! YES ! ! ! The speed sensors was all that needed replacing. NOT ANY SOLENOIDS ! !. Two of them cost $160 and it solved the problem! Do not buy from the dealers. An after market version is available for $50 each. I was forced to buy dealers.
