Intake Air Warmer - Engine won't start if disconnected.

what piece are you refering to? There is no intake air warming unit on our cars. You are probably refering to the power module that is right next to the battery. There is a hose that attches it to the stock air box. The car will not run with the wiring disconnected from it. You should be able to remove the entire stock air box and put in a cone filter setup with no problem, plenty of people have done it. Did you have all the vacuum lines routed properly? A vacuum leak will cause the idle to surge up and down.

On TBI and carbie cars there is an air intake warmer that comes off of the exhaust manifold. Have you checked the temp probe inside your intake housing where the filter goes?

Or are you talking about EGR system parts?

On log cars there was an EGR tube on them. Atleast thats what the book says!

But, an 87 CSX shouldn't have EGR on it....

If the intake air warming unit (never heard of that on a turbo dodge before) your talking about is the part SwiftTech is reffering to then, it should be located behind the battery and have two large wiring connectors going into it. This cannot be unplugged, the circuits that drive the injectors, charging system and many of the other engine functions are in there. The factory ran air through the housing to cool the electronic components off, not to heat the air. That said many of us, myself included have run our cars with a cone filter and no hose to the power module for years without any adverse effects.

When you hook up a cone filter it will need to go to the turbo inlet hose, with the stock airbox gone you will have to put a piece of pipe in place between the two upper intercooler hoses, and also attach a breather to the PCV tube.

Thanks!

Now I know! :bash: Power Module!

Makes total sense now - the unit inside looks like a big heatsink. No wonder the engine wouldn't run with it disconnected.

You guys are great - bonus points! :thumb:

Can we get cookies instead?

I knew TII cars didnt have EGRs, but I thought the logs did. lol
