Just got back from VoTech program which did head gasket, timing belt, water pump. Drove home 10 miles and started a handful of times. Runs rough, doesn't want to idle well till warmed up. Tried to drive over past weekend and the front end locked up (chirped tires at 10mph). Ended up being 8 codes when I put the OBD scanner on. First test codes were P0130, 0136, 0500, 1100, 1101, 1120, 1121, 1540. Cleared the codes which apparently unlocked the front wheels, drove back home. Same day (yesterday) pulled codes again, now 9, not all the same ones. 2nd test codes were P0130, 0136, 0141, 0325, 0500, 1101, 1121, 1507, 1540. Since codes are inconsistent I decided to reset the "computer", so left the battery unhooked today. Will check on status when I get home. Just wanted to run it by some "experts" to see what others thought!
