Bought my 89 in Sept. Has been a really cold nature starter in the morning. After going out to deer lease in East Texas had the chance to really use the 4wheel drive and it started running really rough. On my way home when I stopped at a stop light it would idle down and stall. Took into the shop and they found that the back yard mechanic that rebuilt the engine forgot to install the other half of the intake maifold gasket. Well they also looked everything over and determined that the electric choke isn't working. Wondering if they used the choke thermistat for the electric fan they installed. Has anyone installed a manual choke? Considering on going that way rather than repairing the electric choke.
