CHECK ENGINE LIGHT

CLEANING THE ENGINE



     My 1998 Jeep Cherokee has 160,000 miles on its engine.  My check engine light came on.  My gas mileage was down to 13 MPG  in the city and 18 MPG on the highway.  I used to get up to 22 MPG on the highway.  At $4 a gallon it all adds up.

     If I went to a service shop, I know a $200 bill was possible, so instead, I went to the new local NAPA store in Hastings and started asking questions.  I found their workers quite knowledgeable and they gave me some advice.

      First they gave me a gadget that diagnosed any problems.  I gave them my drivers license for collateral and they told me the gadget plugged in below the steering wheel.  They told me to write the codes down.  I had three codes that popped up.  Next, the Napa agent behind the desk googled the codes.  Yes, I knew about two of the three codes.  My fuel gauge doesn't work, and my two passenger windows also didn't work.  The third code that popped up were my two oxygen sensors located beneath the car on the muffler system.

      After researching the two sensors (newer cars have 4 oxygen sensors) they ran about $65 a piece.

      I don't have $135.  So I continued talking to the gentleman.  We talked about what the car oxygen sensors did.  He suggested to try and clean the MASS AIR FLOW SENSOR  which is located after the intake hose coming off the AIR CLEANER.  He recommended an $ 8 product which you spray on the sensor or spray into the AIR CLEANER HOSE when the car is running.  The product is CRC.  MASS AIR FLOW SENSOR CLEANER.  Yes, he warned me that spraying the product into the air line may kill the engine,  but just said, "Start the car, again, and spray it in there."

     A couple weeks earlier I was at the gas station and a 1998 Blue Jeep in mint condition pulled into the pumps.  The guy asked me how I liked my Jeep and so we talked.  Then he went to explain how he bought this product at MENARD'S, called MARVEL MYSTERY OIL.  Continuing, he told me how much better his Jeep was running.  It was an additive that you could put into the gas tank and add it into your oil as well. .  It was a cleaner.  It was used in World War II.  The product claims it cleans "The Engine from Inside Out."  This stranger told me that his valves and his fuel economy improved.  It cleans the fuel injectors too!  Which is another reason maybe I wasn't getting good fuel economy.   The cost is $ 4 a quart.

     I invested a total of $ 12.  I sprayed my MASS AIR FLOW SENSOR and added the MYSTERY OIL into my gas tank.

     It's been over a month now!  My engine light is off!  I 'm getting 22 MPG again!

     My brother, Shannon tried the MARVEL MYSTERY OIL and his engine light came off too!

     The pay-back for this purchase was to drive 300 miles.  Imagine if everyone increased their fuel economy from 18 MPG to 22 MPG.  I'm waiting for the electric car!!
