Hi

I ve got this problem

when I am on the highway and I change to 5th or 6th and push the gas hard the car goes to limp mode, this happen at about 3000-3500rpm then I turn the car off and on and things goes back to normal.
What I did to try to solve this problem, first I cleaned the maf sensor with Isopropil Alcohol, is something that I rode in other forum which is very interesting, then I checked the hoses, but they where ok. So there is where my experience with engines finish.
In the other gears the engine runs good at full throttle.

Hope someone knows whats its going on

Thanks in advance
:ban

Double post removed, no need to make a separate introduction

Cleaning the MAF sensor can help but it may also do nothing if the sensor is already damaged. It won't hurt anything. To determine if the MAF sensor is bad you must datalog the sensor reading and compare it to what the computer is requesting. If they are the same the sensor is OK. If they are greatly different the sensor could be bad.

Check all the vacuum hoses and intake hoses for leaks and cracks.

Take a look through the limp mode FAQ article and work through the problems. If you're stuck or don't understand anything, please post a follow up.

When you check the hoses, you really have to take a very close look at them. Take them off and visually inspect the ends and then pressure test the hose. They will often crack or split and it's hard to see. This is the most common problem.
