Hey HT, im havin a problem wit my car that recently developed...
When my car is cold, it runs STRONG, no problems at all.
BUT, once its warmed up, it runs like **** under 3k, and once it hits 3k, it runs amazing like it should. But along wit that, the idle is very low and missing. and a lil hard to start. im clueless.

Things i replaced are:
-ECT sensor
-TPS sensor
-Cap, rotor, plugs and wires
-Cleaned the iacv

Thats all that i can think of..
Any thoughts of what it can be??
Keep in mind that its ONLY happening when warmed up.
Thanks!!

P.S.
Just for reference, its a 95 civic wit a b18b1

 

ttt anyone?

 

i think its your o2 sensor what you should try is unplug your o2 sensor start
your car let it warm up and if nothing happens then its your o2 cause this happened
to me with my eg did the samething when warmed up

 

Oh im running without an 02 sensor. My ecu is chipped so it disables it. thanks for the reply tho!

114 views and no replys? any1 have the same prob b4 or know what it could be?

 

chipped but not tuned?

 

check your timing take a timing light to it may be off just a little or may need to be tightened its weird my DA9 does that with a b20 and im getting my timing redone on friday but id look for that

 

never said i wasnt tuned...

 

The first thing i did was the timing belt, but havent put a timing light to it yet... hmm i try that out. Thanks for the reply!

 

did the timing light and adjusted timing. still hesitating :/ just not as bad

 

Try replacing your fuel filter I had the same problem replaced it and ran strong.. It was only like 9 bucks....

 

thanks for the reply! , but did the problem occur only when the car was warm? like mines? cuz the filter is a couple yrs old.
