My temp gauge doesn't work for some reason (new sensors already). So I depend on my temp dummy light. Yesterday I finally got around to installing my ground effects and Aus stage 3 1/4 panels. I removewd the airbox and am now letting the air come straight into the filter housing. When I started my car up after all of that the temp light came on and stayed on. In addittion to that the car is surging on startup and jerking back and forth if you stay off the gas and coast in 1st or second. But the strangest thing is the car feels like it has another 15 ponies? . I didn't have the elbow piece that goes from the air filter housing to the water seperator/intake scoop before because I didn't have it. It ran fine like that even though it was sucking slightly warm engine air in, so I think that is the reason why the car is faster now, since its all cold air now. But what happened to the temp light and why am I suddenly bucking more than before. Tje car always bucks a little bit in first, but now its completely noticeable.

This is a new reman 2.8 with all the usual dressing to make power.

What did you do with your IAT sensor? Where did you mount it?

That is mounted in the air filter housing, I didn't remove the air filter housing or the air charge sensir, just the water seperator/intake box.

I wiggled the temp sensor wires in hopes that I might've had a broken connection, but the temp light didn't flicker one bit. I also disconnected the battery to reset the computer, but that didn't help.

So to review:

My temp dummy light is always on

My engine is surging when cold

My engine stalls at idle when starting up and then idles low and sometrimes stalls.

I press the gas and get a hesitation then the car lurches forward as if catching up to my request to move.

The SES is not on.

The sensors are all about a year old at most. The ignition is also a year, the engine is about 6 months old and all were put in by me.

Is it possible that because I only have the air filter housing connected and no water seperator or air intake that I'm getting too much air? Like running anopen throttle body?

The air filter not connected would not cause this to me it sounds like a bad temp sender sensor or associated circuits being open ,the computer is getting a bad input signal indicating the engine is warm and in turn is dumping too much fuel causing it to surge .Have it scanned and that should pinpoint your problem.

Scanned as in going to a shop and paying $120.00 for them to do it? Odd thing happened today on my way back to work from lunch/dinner, the temp light was off when I turned the car on and the surging stopped. I don't what the hell is going on with this car, but its definitely strange. However it still kind of bucks in 1st gear like always has.
