ok if you have read my other posts Im having issues with my engine heating up.....sorry for starting a new thread but Im having another issue....twice my car has stayed revved up at 2k for 5 min then it lowers back down to normal idle....and twice when I started my car it started up really bad, the idle was very bouncy and the revvs up were slow and very bouncy......anyone know what is wrong with my car now........-=sighs=- thanks in advance

 

alot of the "bouncy" revs ususally come from a vacume leak. As far as the revs going up to 2k, can you make them drop by steping on the gas for a sec... or dose it just fall right back down to 2K? and is it a hard cold start? And as far as your heat issue... TAKE OUT THE THERMOSTAT...hehe... oh and dont use A/C. and check your water pump... hope this helps get from point a to point a1/4...

 

the bouncyness stops after acouple of revs up tho...so I dun think its a vaccum leak....and the 2k rev stops once I get in a high gear and slow down the car while its still in gear. Also, alot of people say not to run without the thermostat.....and Im going to check my waterpump n **** this week.

 

Have you messed with your mechanical or electrical idle adjustments recently?

Does she ever settle down to around a 750 rpm idle?

Unplug the bac valve and warm her up- what is the idle now, with no electrical loads?

 

no I dont think I have messed with any idling things, hmm some water might have fallen on it but could that be the problem? She idles at around 1k...and Im sorry Im sort of a n00b but what and where is the bac valve? Oh yea anf I forgot to mention before, it revs up slowly and the whole car shakes, even mufflers.
