The suspect is the MAF or the connection to it.

I forget to mention the cruise control not working too.

I have written several times before about the capacitor's selection. You need to study a lot about the Bode plot and measure the actual circuit, if you want to use non recommended capacitors. Too low ESR capacitor often causes problems of stability or RF oscillation, you know. Without analysing the relationships between the phase and the gain of the error amplifier, the person would have very hard time to compensate.

Of course it would be nice if you were planning to use non recommended ones and inform us the result with the chart.
Yamae, do you have any chart with ESR values, which is the best for capacitors? I'm asking this because I found few of charts with different values, I would to like measure capacity and ESR before replacing capacitors.
