Small Issue with Idle

[markseven]

Sometimes when I take my foot off the gas, the engine seems like it’s going to stall – the RPMs drop to 500 and then the ECU kicks fuel back in. The engine doesn’t stall and revs bounce back to normal idle. This happens maybe 50% of the time. The other 50% is near seamless redelivery of fuel. Any ideas?

AFAIK the O2 is connected and functioning... I'll check the fault codes just to be sure. It started happening after the road speed sensor was connected... coincidence?

If that doesn't work, check vacuum hose intake.
That was the problem on a friend's car... it wasn't on properly.

Are you referring to the vacuum hose that resides under the intake mani? If so, yeah, it's on tight.
