I Checked what i can
replaced my plugs, fuel filter, checked the wires, adjusted the idle thing by the tb

what else can i check

coz my idle is just so bad, it is ok for like a minute and then it just fluctuates but not by much
maybe from 500 to 600 then back to 700
like it would almost die and all of a sudden just catch its breath again.
whats wrong with my car.
Also the mpg is really bad, about 250 per full tank

 

DId you check the o2 sensor. Thats what happen to my CRX

 

i checked it and it's fine.....i just passed 100k
how long does an O2 sensor last anyway?

 

check the ignition system (distributor, ignitor in the distributor, spark plugs, spark plug wires) like i posted in another thread, same **** happen to me in the high rpms, turns out the ignitor in the distributor was failing. good luck

 

wat should i look for when checking those you have mentioned......
besides idle.....the car runs great......
i jus tuned everything and i just filled up so hopefully i get my great mpg bak

thanks for the helps

 

You might have air in the coolant system. It made my car idle horribly.

 

air in my coolant system>?
IS THAT true....
I have drained and replaced the system a while ago
maybe 3 to 4 months before i started having the idle problems.....

I searched and someone mentioned the vacuum lines that there might b a leak
My pvc is pretty new i remember changing it jus a lil over a year ago.
& i checked my pvc and its working....

one question tho......should the pvc valve be somewhat wet?.....mine was.

 

Where is your engine temp when this happens? Have you checked all of your idle sensors? IAC, FITV, Bleed your coolant..properly

 

welcome to the club, dude... im havin focked up bogging and stuttering problems... both in idle and driving. already replaced plugs, wires, rotor, coil, and cap. inspected map sensor, injectors, fmu, fuel lines, and missing link. i dont know what the fock is wrong with my car!
