I got a p0101 on my scantool. Engine rpm is too high. At cold start it reaches 1500 rpm and in a few minutes will rev high to 2500-3000 rpm and it stays there. I replaced the air filter, MAF sensor and the MAP sensor but still didn't fixed the problem. I also used BG air induction cleaner on the throttle body but still didn't solve the problem. Replaced also the spark plugs and did a change oil. Need help. Thanks
I would first check for vacuum leaks with the syptoms you have with that high idle.A vacuum leak can cause a high idle and skew the map reading and set that code. Also make sure the air inlet tube isnt leaking.

Also pull the vacuum line off the fuel pressure regulator and see if its leaking fuel into the vacuum line?
