I have a 2002 Ford Ranger 2.3 liter engine that did not pass emissions due to code 1537 Herbert's Automotive diagnosed a bad upper intake manifold and I have a intake runner manifold control problem. Apparently in Ford Rangers you can't buy the parts separately. I need a good and fair mechanic who wont charge me too much to get this fixed. Contact Caroline at 407 459 5632 in the Cumming area.
