I OWN A 1997 FORD RANGER WITH A 4.0L V-6. THE ONLY THING WHICH I NOTICED WAS THAT WHEN YOU START IT COLD, IT WAS JUST THAT. BUT WITHIN TWO MINUTES IT RAN JUST FINE. NOW HERE IS WHERE IT GETS FUN! THIS MONTH IT WAS TIME TO RENEW THE INSPECTION, AND THIS IS MY STORY. THE RANGER FLUNKED FOR THE FOLLOWING REASONS. THE CHECK ENGINE LITE WOULD NOT BURN, AND THE COMPUTER INDICATED THAT THERE WAS A PROBLEM WITH A CODE INDICATION IT WAS RUNNING TO LEAN. ALSO THE GAS CAP WOULD NOT SEAL AS THEY THOUGHT IT SHOULD. GAS CAP = MINOR PROBLEM. HOWEVER WHEN I CHECKED INTO THE C.E.L. I FOUND THAT THE BULB DIDN'T WORK. ANOTHER EASY FIX. HOWEVER AFTER THOSE TWO EASY FIXES I TOOK IT TO THE DEALER FOR THE C.E.L. AND HERE IS THERE REPLY. BECAUSE OF THE RUNNING TOO "LEAN CODE" THEY NEED TO DO THE FOLLOWING: CHANGE OUT THE O-RINGS ON THE INTAKE, REPLACE THE OXYGEN SENSORS ON THE EXAUST, REPLACE THE SPARK PLUG WIRES, REPLACE THE GAS FILTER, THE LIST CONTINUED HOWEVER I STOPPED HIM AT THIS POINT. I THEN ASKED WHAT ON THE LIST WOULD NEED TO BE DONE TO TURN THE C.E.L. OFF. HIS REPLY WAS A MINUMUM OF THE FIRST THREE ITEMS ON THE LIST. NOW FOR THE REAL FUN! AND ALL OF THIS FOR ONLY $ 950.00 U.S. O-BOY O-BOY ( DID I TELL THEM I WAS COMING OR WHAT? )
