I have a code for a MAF sensor. The code said that it read low air pressure. The check engine light will turn on and off with no difference in how my car drives. I cleaned the sensor and changed my air filter and it worked for getting ride of the light for a day or to. The only problem so far is when I first start my car and push the accelerator the rpm needle goes down then a second later it will jump to about 1500 or 2000 making the car lurch forward. So is the MAF sensor code and the car driving weird have any relation and if so how can I fix it. Thanks
