I had the lifter failure at 90,000 with my 19 Silverado. Mechanic got it all fixed up but instead of taking it to the dealership to have the computer re programmed, he was told by his "computer guy" that you just install the Pulsar LT and I wont have to spend the high dollar cost at dealership to have them do it. All was great at first but I noticed the oil alert would go back to 9% right after it is reset, also the Change air filter alert was doing the same thing, I could reset it and it acted normal but next time I start it up, the Change oil and change air filter alerts were back on. On the fourth day, I was driving home and it went in to reduced power mode and said service parking brake and service ecm I think? Anyone ever heard of using the Pulsar for this? I think it is causing the problem. Mechanic replaced lifters, cam, cam bearings and crank bearings. Help! I want my truck back!!
