I got a d16y7 and it was running perfect until I swapped a y8 intake mani on it. It popped a cel and starts running rich as ****. I changed the o2 sensor and spark plugs and it still runs rich. What else could be the problem? Injectors? Fuel rail? Fuel filter?

 

Neither, a faulty MAP sensor (also TPS in some cases) will cause you to throw in more fuel than what is needed. Also, check to make sure you have the intake manifold bolted down tightly and properly, because vaccumm leaks can cause poor performance as well.

 

map, or tps? What does the cel say?

 

Mani was installed at a shop. At first it was leaking like crazy because there was little holes at the bottom of the manifold but the shop welded them up.

Cel code is like #45 which is system running rich/lean.

So most likely it is the MAP or TPS sensor causing problems?

 

Probably so.

 

a Bad map sensor will cause ur ECU to toss gross amounts of gasoline into the cylinders.

 

Alright thanks for the help.

I found the MAP sensors online but I couldnt find a TPS sensor. Anyone know where I can get one? Thanks for the help.
