I was driving on highway the other day when my tire popped. At the same time my check engine light came on. I took it to autozone and got it pulled. it was something to do with the air/fuel. The car runs great except once its warmed up it has a bumpy idle when i come to a stop like it starts at 1500 and drops to 1200 then back up to 1500 for about 20 seconds then it settles back to about 800. \

Does anyone know whats wrong with it? TIA

 

i have that same problem in my DA with b18c. I dont know what it could be ? maybe the TPS ?

 

anyone ?

 

o2 sensor maybe, since that controls the a/f ratio.

 

Also wondering what it could be. I highly doubt its the o2 sensor. I have a p28 which doesn't use an o2 sensor and mine still idles like that.

 

bump

 

i have a chipped p28 and it does the same thing when i come to a stop it idles from 1000-1300 then goes to 750 after a few seconds. but i dont have a CEL

 

I still fdont know whats wrong. also i have noticed a severe decrease in power almost like a misfire.

 

Idle Speed Control motor??
