I purchased the max-scan scanner and I have hooked it up when the car acts up and the only code that is there is for the secondary air pump incorrect flow. That makes sense since the air pump is not currently on the car.
There are no other codes present.
I have read that a few other people on this forum have had similar issues and it has been the camshaft position sensor.
I have recently had the engine out of the car to replace the front seal in the trans. (01M, auto).
At that time I also replaced the water pump timing belt and the tensioner pulley. I have replaced a couple other things as well. Like the temp sensor and the fan switch on the rad. I also have replaced the engine rear main seal when the engine was out. replaced the valve cover gasket and a couple bad vac hoses. I had probably put about 1500 miles on the car before engine removal and I had not had this issue brfore I took ouot the engine.
