i have had this vechicle for 7yrs now running it everyday small trips. this van at one time ran on propane you can tell by the way the connections are wearing. since last post i retrieved the codes faults from smec used on off methodsurprised it worked. 37 part throttle unlock solenoid circuit and a 52 oxygen sensor which i already have changed. where and what is that 37 part. i did clean the one solenoid block though did not check it electrically yet. thanx semper fi .
