Hi guys,

May remember me. I'm the guy who had an occasional idle fluctuation when the rad fan turned on. Never got that one worked out. Now I have an issue that I think may be related, but not sure.

Ok.. So, when its doing its crappy idle thing and I gun it in park, it will NOT go past 4000 rpm no matter what.. Its like vrr vrr vrr vrr .. No smoke, nothing to funny, just wont get past that point! Its not smooth.. it definately a vrr vrr vrr vrr thing.

What the heck is up. Its a 2002 SES (has the lower powered v6) that, UNFORTUNATELY, just went out of warranty and the dealership always told me their was no prob. I wish I had tried gunning it before. I never noticed because I dont usually gun it in idle.

I'm wondering if its an intake sensor.. crank sensor.. ?? I'm such a rotary engine guy I have no clue on piston engines anymore

Anyone know whats up???

p.s., the battery light does NOT come on when it does that. I only say that because my brother had a bad regulator on his 2000 and it would kind of cause the same thing becuase I guess their is a switch that cuts juice when your regulator isnt regulating anymore and your rpms up the voltage to a dangerous level.

oh well.. this is so bumming me out.. grr

my 96 GL does that too i try to rev it past 4 k rpm in park it starts to like choke for air or something...

someone here in the board told me its because of the rev limiter...

Ya it won't go past 4k when in park and 2k when in drive with the brakes on. Its the rev limiter.

That's right. It won't let you do it because you're not supposed to do it. It's like a safety feature for the engine.

ok. now i feel retarded.. LOL - Makes sense ;-)

Guess I'm used to reving my rx up to 8000

I just drove home and gunned it out of a light and it went up to 5000+ and I was so perplexed

Rev limiter.. sheesh

Just call me Newbie

No problem. It kind of confused me at first too. You can always add a chip or get a reburn to eliminate rev limiters.

If the rev limiter was removed how many rpms do you think the car can safely be dropped from with the break applied?

I dont think you can change the torque converter stall speed with a chip. I believe thats what keeps you from going past 2k rpm while holding the brake in drive. You'd need to change the torque converter to one with higher stall speed.

what is stall speed? just wondering, how does the converter stop the engine from running past 2500?
