my car will not idle until I've held the gas down for about 5 to 10 minutes at about 2.5 to 3k rpm. after 10 minutes it idles fine. What would cause this? Thanks.

Throttle-body mod?

Malfunctioning thermowax?

The Haynes manual and FSM has a detailed procedure on checking the thermowax for proper functioning. Check it.

what is the thermowax? I don't believe I have the tb mod. is there any way I could check? Thanks.

if you are not holding the gas, what does it try to idle at ? 1500 or 750?

what rpm is it at while you are holding the gas.?


even if it was the thermowax it shoudln't take 10 mins. more like 1

in all likely hood it takes until my temp guage is almost a quarter of the way up for it to start idleing. When it does start to idle it idles around 750 and 800rmp. Not a bad idle at all just takes a while. I am reving it at about 2.5k to 3k for about 5 to 10 minutes.

oh and if I don't hold the gas it will die.

Does the car have a steady idle once it's warmed up? If not, it could be a vacuum leak somewhere.

yeah perfect idle almost.

anyone?

I have that exact same problem....however, I have done the TB mod, so I assumed that is what was causing it.

hondahater

how can you tell if you have the tb mod? I know I didn't do it however maybe the guy before me did it. Thanks.

Well the thermowax is this thing (don't know how to describe it lol ) that has wax in it, and it holds the throttle plate open a little bit, like you have your foot on the gas, which speeds in warming up the car. When the car is fully warmed up, the engine heat causes the wax to melt, and the throttle plate closes. I'm not sure where it is on the car or what it looks like, but that's what it does !

ahhh thanks! that would make sence! now we need a pic

Thermowax? Is that the thermowax pellet?

hondahater

iTrader: (2)

don't know but someone should know about this problem! No one else has this problem?

JanusRN

Actually, the reason I ask is because I have pretty much the same problem. On a cold start, if I have to sit and keep my foot on the gas some or else it'll die on me until it is properly warmed up and idle on it's own.

I don't know I used to not have to do it that is why this seems rather odd. Maybe someone could tell us where the thermal pellet is

Its the thermowax/fast idle cam that is located on the throttle body. Its shown in the fsm in the FUEL SECTION. There the fsm describes how to set/rig it.

check and adjust BAC. Even without thermowax it should idle. I have 2 rexxes, both without thermowax and the tb mod is done. One idles right away, one doesn't. The one with the BAC idles and the other doesn't. Also make sure the coolant is still going to the BAC

hondahater

iTrader: (2)

huh? Sometimes the coolant stopes going to the bac? Strange what would cause this? I'll check as soon as it comes back from the body shop. Thanks.

HAILERS

Water flows from a nipple on the rear housing....thru the thermowax...to the pipe on the side of the bac....to a nipple on the rear of the water pump housing. The flow is in the direction stated above.

That said, the water pipe on the side of the bac has little to nothing to do with the operation of the bac.

But, if there is little or no flow out the hose attached to the bac...that means the path is obstructed in the throttle body most likely. An obstructed water path will make the thermowax be disfunctional.

Remove the throtte body.

REmove the thermowax from the throttle body.

Clean the passages in the throttle body.

Reattach the thermowax and rig it.

Put everything back together and see what happened.
