i recently did a head gasket on this car and replaced the timing belt. upon successfully starting the car and adjusting the valves, i took it for a drive. at idle it runs fine. about 2 minutes into the drive (not sure if this is time or speed related) the check engine light would go on simultaneously as the car would lose power - as though a cylinder stopped firing. after getting home, i check the ecu. it claims a crank angle sensor fault. this is located in the distributor, which is only a few months old, and is unreplaceable according to chiltons. if i clear the code by pulling the hazard fuse for 10 seconds or so, the car starts up and runs great. again, it idles fine, take it for a drive, about 2 minutes later, bam, check engine and power loss. now, the ecu has been known to be wrong before. any ideas? thanks so much.
