guys, my engine has been idling rough lately, I am noticing a hissing noise coming from behind the intake manifold, and I have lost a little bit of acceleration, plus a little bit of backfire. Now I know thaT Backfire is caused by leftover fuel that wasn't burned.
so my question is, Is there some kind of sensor calling for more fuel? Is there some kind of vacuum hose loose? any ideas would be helpful oh and I've heard that the check engine light usually relates to pollution control devices in the engine. please help me with any ideas. -Jim -------------------- [img]http://photos-081.facebook.com/n6/081/n15913038_30266081_3342.jpg[/img]

Most probably the vacuum hose to the fuel regulator.
i may be round. THe MAP sensor would not do this since you have a very low pressure drop occurring to give you that hiss. If it is the vacuum hose to the fuel regulator, you will run rich and idle ruff. I call that good/bad fuel addition. I use to run my 4AGE 20v Black top like that, except I block up the vacuum hose |
