I helped a friend replace the plugs on his Mazda 6 tonight, and now it wont run. It is a first gen, I don't know what year, V6, Auto with an AEM CAI.

He read the write up posted on this site as a guide before he started. He is mechanically inclined as am I. The only variation from the write up is that the three 8mm bolts on the EGR would not come off, so we took out the two 10mm bolts and pulled the EGR from the bracket. Everything was put back together correctly. AFAIK

The car barely runs. The engine comes close to dying, then revs, then repeats. It almost sounds like it's sucking air, but I can't see where. There is an odd "taping" at the TB and EGR. When the car is turned off, the EGR makes as rapid click, then it stops. I need help with this. Anyone have any ideas?

Thanks

Check for a pinched wire harness under the intake manifold.

Check all the EGR connections, and all FOUR of the hoses connecting into the back of the intake manifold.

It sounds like you also have a vacuum leak.

yea. def sounds like a vac leak. take a can of starting fluid, and lightly spray around the EGR when the car is idleing. if the idle raises when you spray near the EGR, that tells you your dealing with a vac leak.

I had a similar issue when I did mine, and I ended up forgetting to hook the hose back up that is at the bottom of the throttle body.
