well i just put my rebuilt motor back in the car with a new clutch and it fired right up thank god (first motor taredown) i took it for a ride around the block idle is good but it gets warmer then it used 2 i am thinking i need 2 burp it a couple times to get the air out buti will be driving and once and a while it will start to chug a little i took it on the highway and it ran good and then chuged for a sec or 2 and then stops and keeps repeating this?? i am kinda leaning 2 the O2 sensors what ya think??
