OK, guys, not another bad weekend, please. I have a lot of writing to do this weekend. But the car complains.
Short story: the car hesitate during acceleration, check engine light on, yellow, steady. It never goes higher than 3000 rpm. But it can go to at least 75 mph, no problem, just slower because of the small rpm number. Haven't had the chance to get code yet.
Longer story: as you known, this is my 96 bonne with almost 138 k miles now. I just had it for about a month now but only really started to use it two weeks ago for some reasons some of you may still remember. I commute 130 miles round trip each day at 70 mph. I changed the oil and filter two weeks ago, with the famous auto-rx treatment. For those http://www.bobistheoilguy.com/
members, I am sure you are very familiar with it. It is supposed to clean up the engine and make it run even better and receives unanimous praise there. That'* why I thought it must be a good idea to use it for a high mileage car. But now I am afraid it has something to do with it. The oil and filter used were cheap walmart supertech because they should be changed out in 1500 miles, or 200 miles later. So the filter may have been clogged enough but oil pressure is fine.
The car started to hesitate a bit during acceleration sometime this week but I didn't pay too much attention. Today it declined to go higher than 3000 rpm and the check engine light came on. It still drives fine and I came back home with it, still at 70 mph. Back home earlier is more important, isn't it? I don't know how much damage has happened though. No other warning sign.
Anyway, any thoughts? Thank you very much!
