I really didn't want to post on the Mustang forums, because from what I've seen their information isn't that good. It seems to be a bunch of 16 year olds that just throw random information out there with no help. I've had better luck on here, plus I think the Ranger guys seem to know more about vehicles.

Ok so I got a 1996 Mustang GT that still had the original plastic intake manifold. I bought a Dorman replacement that has the aluminum cross over since mine was cracked in the front and near the heater core nipple. Before the swap coolant was pooling in the #4 spark plug hole (rear passenger). So as a temp fix i pulled the boot and filled the crap out of it with dialectric grease. Worked pretty well.

I finally got around to swapping out the intakes and took my sweet time to cleaning everything up with carb cleaner, especially where the intake meets the heads. Problem is that the car runs a little rough, starts better than ever, but seems like there is a loss of power through out the whole RPM range.

When I did the swap I removed the spark plug wires with the wire guides still connected. I'm almost 100% positive that I put the wires back in the right locations I double checked the numbers on the wires and the numbers on the coil packs.

I'm wondering if the metal connectors in the boots probably got tore off when disconnecting them. They seemed to "snap" right back on during installation.

Also, could I have switched injector plugs on two of the cylinders. I remember two on the passenger side being really close together but one sort of seemed to go one way so I installed them that way.

NOTE my gf said she saw "exhaust" coming out the passenger side tailpipe but not as much from the drivers side. So I'm thinking the passenger side is burning rich.

What are your guy's inputs on this matter? Thanks in advance.

 

Ok problem solved. One of the vacuum lines got torn when the new alternator bracket was installed.
