Expert:  Tim's Auto Repair replied 11 months ago.


from the way you explain the problem and from the codes you are getting,

the first thing to try here is to clean the throottle body,,the throttle body can get dirty with black soot and cause these problems,,

if cleaning doesnt may need to replace the tpps.
