Hi Archie,

It is possible that your brake master cylinder is leaking brake fluid into your power brake booster. Your power brake booster is connected to engine vacuum so if a flammable liquid such as brake fluid were to enter the power brake booster, the engine would be able to inhale that fluid.

When the excess ’fuel’ is added to the engine, the powertrain control module (PCM) will increase the idle speed to compensate for this extra ’fuel’. I would recommend to check the brake master cylinder first and check for any vacuum leak. 

Let me know if you have further questions.

If the brake master cylinder needs to be replaced the price range for the part is between $190-$220. The installation/repair cost would be around $150-$200. The cost for the vacuum leak diagnosis is between $88-$115. 

Let me know if you have further questions.
