1994 ZJ 4.0 MAP Vacuum
Hello. I'm having rough, low idle issues and I've been running down problems all month long. Replaced IAC, TPS, and O2 sensor. Today I'm replacing the MAP sensor and come to find out, there's no vacuum line on it and I don't know where the other end is. Help?

The other end goes to manifold vacuum. So now you threw a bunch of expensive parts at it when all you needed was a dollars worth of vacuum hose. Diagnostic work saves money.
