The latest truck is a 97 215 4x4 5 sp! Getting tired of electronic injectors! The post I quoted so far explains it the best. Thanks to all the resonses. I bought the truck on July 17 09 i drove it today with every thing fixes! KDP , 16.5 timming , timming cover seal leak, HX 40 ( 60 mm) wheel , gauges, exhaust gaskets, 4 inch exhaust, cleaned exhaust manifold, white gauges in the dash, oil change ,filters change , battery cables, steam clean 3 or 4 times, The owner before me ( 1 owner truck ) Had the oil pan gasket replaced 3 times still had a leak! timing cover was caked almost 3/8 of a inch of sludge! Also a # 8 plate full forward. When i put the AFC on i slide it full forward, didnt touch the star wheel , NOW I HAVE TO TUNE THE AFC! Also I need a Dana 80 locker or? spins the tire way to easy. No plug and play here tuning takes time!:thankyou2:
