Thanks for your prompt response, just to give you and update before I answer your question, I replaced fuel filter, cleaned EGR and Throttle Body, as well as the MAF sensor a second time but thouroughly. I cleared the codes since then and so far so good. Now to answer your question first the MAF did'nt malfunction till I installed the K&N but since I cleaned it that may have been the problem, (wait and see), secondly the car doesn't constantly run at 250 maybey for a minute or two, (need to check fans) i've never had a V8 so didnt know if that was normal, now I called Cadillac (cause oldsmobile no longer exsists), and they tell me that anywhere between 180- 220 is normal operating temp for that vehicle but not uncommon to temporarly exceed that. Thats what the aurora forums are telling me too. But I thought the same with the boiling boint, it doesn't make sense, but their telling me that Northstar Engines always run hotter than normal v8's. What do you think should I replace the Thermostat or start looking further?
