ECU is like your mother board and inside there is a PROM which is coded for your cars engine type and size etc. This prom keeps the systems as they should be like during warm up highway driving etc. Takes info from all the systems and makes fuel mixture, timing, and other adjustments to keep the car running correctly.Your prom needs replacing I think. This has to be done very carefully, Maybe best to take it to a shop.
Hope this helps Mike
