1999 Mazda Protege 5spd. 125,000 KMs Engine light has come on and stayed. Replaced the EGR Valve. Light went out. Week later, came on and stayed. Drove it this way for a couple weeks, then tonight, started real rough and light started flashing. Light flashed all the way to the mechanics'. Any ideas what causes the flashing light, and how serious this would be? Thanks!

Well.

How good is your mechanic? Why was yor EGR valve replaced? EGR valve are common on those engines. But so are ignition coils. Ahev him check hte coil and wires to see if they are firing properly and find out what the code is before you reply to this

Have it scan and comeback with the code or codes, if its an EGR problem it will fall between these codes P0400-P0408.

Try this tap the EGR while its running rough, if its smooths out, you've found your problem-if not open it up and check thoroughly for excess carbon at the pintle, intake and exhaust manifold sides. If all these checks out, then we'll go somewhere else, this is just the start. But we still need the codes-take it to autozone its free, just be nice to the partmans that way you wont have to buy something.
