Hello there, first time poster here at the forum, I’d like to know that my car is not about to die on me. I have a 2006 Pontiac Grand Prix, it’s got about 193,000 miles on it, automatic transmission. All the miles are highway miles from the interstate, and I keep it well-maintained
Earlier today I got on the interstate to drive to work, and as I am on the interstate I got my car up to 75 miles an hour which is usually my speed on the interstate, all of a sudden I could feel the engine beginning to slow down and as I look down I saw the check engine light blinking on and off.
Now suitably freaked out, and worried that my engine is about to be in 1000 pieces when I get out of the car, I pull over to the shoulder popped the hood look in and I see nothing is wrong. Engine looks fine I smell no smoke or no steam or anything else, it all looks the way it should. I got back in the car turned over the motor which, turned over just fine, got back onto the interstate and made the drive to Knoxville (30 miles) in the car handled perfectly well. It drove just the way it always did, I didn’t feel any shaking are generating I didn’t hear any misfires or didn’t hear the transmission struggling to shift gears. It just drove the way that it should. Which is good for me
Anyway I had a few minutes to kill before my shift at work started so I quickly checked and I found out what it was in is limp mode, which happens to a car if the transmission is about to go down and it’s getting you home. But I think it’s just a bit of a fluke because once I turned off the motor and turn it back on the engine light turned off and it let me Drive normally.
I need to know, should I be concerned about this, should I take it to a mechanic I don’t know what to do. The only problem is I’m saving up my money for a big trip in August and I just got this car paid off. And I don’t want to see my entire vacation fund get obliterated because of this. Any advice you guys can give I would be greatly appreciative.
