Hey all.. newbie here so please be patient .. someone must have seen this before ??

Got a problem with my car not idling properly.
Everytime the car comes to a standstill it idles at around 3000 rpm for a few seconds ... then 1500 rpm for a few seconds.. then settles at 1200 rpm..

Sometimes it will even idle very low eg. just under 800 rpm and the car feels like it wants to stall.

Only thing I have noticed when looking under the hood is that the casing for the TPS (throttle positions sensor?) plug is broken / cracked... it dtill plugs into the sensor at the throttle body fine.. Nothing seems to be broken or loose..

Anyone got any ideas of the problem? I will replace the TPS plug to be sure. Also someone has told me to check the oxygen sensor?

Thanks in advance.

do you have any mods done to the car..FPR or a different ECU

 

usual intake / exhaust. Also got upgraded fuel pump as well. Running standard ECU. BTW .. the engine is in a second generation CRX ... I don't hink it'll make any diff.

Started after me gogin to the drags ... maybe i broke something??

 

is it throwing any codes?

 

There are also problems with the distributor going a little crazy if the engine has been sitting for an extended period of time. A friend of mine had the same problem on his B16A, we just replaced the distributor and it was fine. Let us know how it goes after you replace the TPS.

 

Thanks for the tips guys ..

Will let you know once parts have been replaced.
