Manual or automatic?
Clean the MAF sensor first, they need to be cleaned every 5 years or so.
Check the voltage on TPS(throttle position sensor).
It has 3 wires, top, bottom and center
You want to test the center wire
Remove throttle cover
get a sewing pin and pierce the center wire
Set volt meter to DC volts
Turn on key, engine off
Ground meter(black probe)
Touch red probe to sewing pin, it should read .69-.99 volts, under 1 volt
Now while reading the meter slowly open throttle manually
Voltage should go up steadily, no jumping around and no dropping out
When you get to wide open voltage should be above 4.5volts, 4.50-4.90 volts
