I did a MPFI swap on my 90 DX had a couple problems but seemed to get everything worked out I had the car running for about 15 minutes in the driveway yesterday and was revving it up no codes appearing then after a few more minutes the CEL comes on giving me a code 4 crank angle sensor?I used shielded cable for crank angle sensor and cyl sensor with each grounded at one end.Anybody have any idea as to what is causing this problem?Thanks
