2001 oldsmobile intrigue 3.5
hello
overheating probleming removed t state and i have good flow threw. when the cap is off seems not to over heat but when cap is on it heats up quick. also at 4000 rpm it drops out like plusing any ideas

Have you tried replacing the thermostat with a new one?

If your reaching 4000 rpms in either Park or Neutral the engine is doing exactly what its supposed to. It wont rev higher than 4000 rpms in those situations.

Or are you talking about the engine begins to run rough after 4000 rpms?

If you figure out the overheating issue, let me know. Mine has been doing it since this past winter. Would always do it on very cold days, below freezing. Now its doing it when its really hot out, 85 and above. Between those times, not problems. I tried 2 t-stats and everything else I could thing of. Very strange problem these 3.5L have and NO ONE can give me and answer to what is causing this. There is never a rhyme or reason because sometimes when its hot out, it runs normal. Sometimes having the AC on causes it to get hot, then the next time it makes no difference. I have had it to the GM dealer and to a cooling specialist and neither could get it to overheat. It just was one of those days when it decided to act normal. Its like they know when the mechanic is looking them over. Very frustrating

I told my wife, drive it until it blows up or until I can find a cure.

hi, I just got a 01 Intrigue, and it has a little over 93,000 miles. the transmission was just rebuilt last year, and now the engine is making a sort of loud knocking noise, but only when you hit the accelerater. (if it's idiling, it's fine). I have a feeling that I will need to replace the engine, but 1) does anyone have an idea of something else that could be causing it where I might not have to replace the engine? 2) does anyone know of an easier way to change the engine besides the large thourough process of taking the whole front end out? thanks

Not a problem. We no longer have any rules prohibiting resurrection of old threads as long as it is not way off topic and the member needs help. However, whenever possible it is a better idea to start a new thread.

You can buy a dandy OBD2 reader for $60-100, plug it in and read those codes. I like the Sears Craftsman one for $90 with the DVD and computer cable. Autoparts stores will OBD2 scan you for free -but I would call ahead to check first.

Sounds like a catalytic.
