After several post in this forum I finally fixed my Prelude "Idle & Stalling" problem. All it took was a fuel filter. I purchased a EGR Valve, Map Sensor, and a Chipped OBD1 ECU which worked but the car ran bad. As soon as I started the car with the OBD2 ECU in after changing the filter I can notice a big difference.

Now all I have to do is figure out why my ECU keeps throwing "Random misfire codes and I will be ready to start adding mods to my car.

 

Thats why you replace the cheapest stuff first then work your way up

 

It's really amazing all the problems caused by a bad fuel filter, and they're all so misleading.

Can't really blame the filter, unless there was a factory defect (which is rare). Otherwise, the only way a filter will go bad is if you let it go bad by not replacing it on time. $25 and 10 minutes of your time - that's all it takes to prevent this from happening.

But yes, I agree. The problems caused by it can be misleading.

 

It's still throwing codes so, I am going to replace the Air Filter now.

 

Adjust your valve lash.

I am sorry but what is a valve lash?

 

it's the clearance between the rocker and the camshaft. I agree with cuz that solved my random misfire code. basically adjust the clearance to spec.
