so I’ve progressed from P0171 and P0174 to P2195 and P2197. I had put in a new hose from the air intake to the connector to the brake booster and PCV. I was looking to see if there were cracks or leaks. I noticed the connection to the brake booster wobbled a bit. Then I started the car and tried to rev the engine and no response from the accelerator. Any more thoughts?
