My 89 cherokee will start and run fine, but after about 10 minutes it develops a miss and starts smelling of raw fuel. It will do this sometimes for the whole drive or 10 seconds and goes away. Consumes a lot of fuel when missing! Any idea's. Replaced cts & map sensor no fix. Also the tps has been replaced with a new two plug for autos or manuals, does the ajustment really do anything in this sensor if so how do you set it?
