A ayang89 Member : 2003.5 Mazdaspeed Protege #1827 Jun 24, 2015 #42 Update: Went and got a MT Ecu from a 2.0 protege. Took a few cranks after resetting the ecu for it to fix itself. But it has a terrible idle issue. Which would cause it to jump to 100rpm, turn on the dash lights real quick, then fix itself. Gonna clean out the egr and see how that goes. Becoming a bigger pain then expected.

A ayang89 Member : 2003.5 Mazdaspeed Protege #1827 Jun 24, 2015 #43 Update: Cleaned out the egr. Helped alittle bit. Not worth the 1 hour trying to pull the b@$!# out. Car still has the boost gauge connected. Its reading a vac of -12. Is that correct for a N/A car? Cars also got a CEL. Havent gotten time to run to autozone to get it pulled. Any thoughts on the vac read?

H hornsfan10609 Certified Mazda Tech : 2003.5 Mazdaspeed Protege x2 Jun 25, 2015 #44 Vac should be 21-22 minimum on a healthy engine, you have a massive leak which is messing up your idle.
