1:20! You can clearly see my car bogging to 500rpm; and almost at the point of turning off, it gos back to normal (1000rpm)????? please help??? any suggestions would be greatly appreciated!

 

My HF did something very similar to this. I went to Autozone, checked my battery and alternator. Alternator didn't pass. I replaced the alternator with a refurbished one and adjusted the idle to factory specs and haven't had an issue since. So I suggest you go to your local Autozone or wherever they do free battery and alternator testing first. Good luck.

 

What he said^. Bring it to autozone or wherever & get the alt+bet tested. If it clears move on to check if you IACV is clear I would guess next.

 

Thanx for the info! Ill be in autozone ASAP.... Im sure its my alternator.. battery is about a 1yr old.. so I dont think its that, and I have heard of the IACV and will have it cleaned aswell!
