anyone have this notorious idle fluctuation on ur b20b
my setup is b20b in 92 dx hatch.. I check the iav and fast iac they are ok.. bleed the coolent..adjusted the idle.. it seems to idle fine most of the time but it fluctuates here and there and sometimes stalls... especially after warming up.. and I sometims get a check engine code 43...
anyone with any ideas??

 

Probably not the problem but check your fuel filter. Maybe there's a bad sensor here or there?

 

you check your tps sensor?

 

tps sensor?
no, check your tps reports. i hear you've been havin problems with those. i'll make sure you get another copy of that memo.

im sorry, i had to.

 

43 is fuel supply system
its probably unrelated to the idle
you might have a vacume leak.

 

tps report wat do u mean??

 

i have to throttle body and they both do it so i dont think its the tps.. although it mgiht be.. I'll double check..

 

I've just change the fuel filter.. i've checked for leaks but I'll check agian just in case..could the purg evap cause the problem??
