I found it!!!I am having the same problem. I haven't checked anything yet except the injection timing, somebody said that could be the issue as well. I could have sworn the link to the diy thread was in here, but Im not seeing it?!
Anybody know the thread im talking about? It walked you through the step by step with or without the service manual...
Yes I did try searching...
2a: Locate the "blue" and "red" hoses under the hood. Also locate the small diameter black hose at the center/rear of the engine compartment which connects to one of the black plastic intake pipes. If the latter black hose is not connected, there is your problem! If it IS connected, unplug it from the intake pipe and see if you can feel leaks by blowing into it by mouth. Leaks? There's your problem - replace it (or plug it in at the other end, if it has become disconnected at the ECU). No? How well does the hose fit on its connection point? If the rubber is hardened up and not sealing well, replace it. It is absolutely critical that there be no leaks anywhere in this hose or its connection points.
If I am understanding you correctly, the end of the black hose should connect to the small hose barb on the corner of the boos piping, near the intake manifold.Old thread, similar problem: my small black "2a" hose is well connected to the small plastic tube that goes into the firewall but is disconnected at the other end-where is it supposed to be attached to?
