what would make my car be idleing like this? It sucks I'm ripping my hair out over it.

 

vaccuum leak, bad timing, the green gobblin

 

would wd40 pick up the vacuum leak if I sprayed it around there? Thanks!

 

B12 would...

 

A bridge port.....LOL

 

lol, common I really need to know this is getting on my nerves cause I don't want to fork out the cash for a new motor but if I have to I guess I will. GRRRRRR

 

incorrectly set TPS and or a vac leak.

 

Malfunctioning TPS. Try driving with the TPS unplugged and let us know if it makes a difference.

 

ok ok ok like I said before not new to rx7's just new to mechanics (sorry). Where is the tps? and if I unplug the tps would it idle correctly becuase right now all interior is out for cleaning. Thanks.

 

I fail to see what the interior has to do with the idle.

N/A or TII?

N/A is easy to spot. TII you have to remove the TMIC.

 

I have this same problem..but only occasionally. Maybe 1 out of every 10 times i start the car it does this..for maybe 2-3 seconds. I'll fiddle with the tps more later though...no time now (school sucks).

Btw, if the car is driven with the tps unplugged...what should happen? A little more theory behind why certain things happen the way they do would be appreciated...that way i can form my own conclusions and u know..be like u incredibly smart rx-7 people

 

the reason for idle is that if no seats, ac, instrument cluster, dash, etc... only thing I can do is idle in the garage its not really driveable the way it is right now

 

oh ps its a tII with a front mounted intercooler. actually the stock intercooler but rerouted to the front.

 

I'm not incredibly smart. RETed and NZConvertable own me!

Amur_ had a thread recently on exactly what you described.. I believe the new (correct) TPS solved his problem.

I would have thought the car would stall with no TPS signal, but apparently it keeps in ticking. But you get a crappy throttle response when you open it up from idle.

*starts looking for Amur_'s thread..*

 

sounds like me right now the throttle response is real bad!!!

my idle is like 20 to 100 rpm realllllllll low not that high. its like brap..pap..pap...brap...pap...pap and on and on. This happens every time I start up my car. so its not intermitent it always does this, thanks.

 

The only GOOD way is a nice bridgeport.
All the extra fuel/air makes it REALLY lumpy. Like a stroked V8 with a cam.

 

... You do realize it takes <5 minutes to adjust the tps?

 

my bridgeport goes brap brap brap..

 

it seems like it will idle like that while cold but as soon as it warms up to normal temp. it won't idle at all? Anyone? Thanks.

 

umm, sounds bad. did you check for vacuum leaks yet?

 

no I will do that tonight! I thought if it was a bad engine it wouldn't idle period. at least this one idles up until it warms up. Thanks.

 

I did that already..twice. Got that bad boy to 0.999
It could be a bigger problem...im gonna take a look at Amur_'s thread like Black13b said.
Oh thanks Black13b for the link by the way.
