I have a 2001 Mazda Tribute with 94,000 mile on it. I've had some check engine light problems, and when I had it serviced, it showed that I had some bad oxygen sensors. When replaced it ran ok for awhile then engine light again. I was told to replace egr sensor. Did that and it blew a hole in the egr valve. The car won't idle right, in the morning I have a hard time keeping it running, :arrow: it won't take hill, small or large and it shuts off when I stop. I since replace the egr valve twice and twice it blew a hole in it. Now I'm smelling fumes in the car and the car now makes a whistling sound sometimes when I accelerate. Please Help, I'm running out of money. P.S. You have my word that I will send you a donation in the near future.

Did they check the catalytic converter, backpressure over 3lbs is an indication of a restriction with the exhaust system.

A leaking EGR while at idle or at a stops will act like a major vacuum leak and also prevent starting.

Another big probelm with those engines was the IAC motor (silver tube on top of the tintake near the throttle body) would stick open causing alot fo running problems

Suggested Repair

Check catalytic converter and exhaust backpressure; restriction above 3 psi can damage the EGR. Also inspect for a leaking EGR, which acts like a vacuum leak at idle and stops, and test the IAC motor for sticking open.

Conversation Summary

A 2001 Mazda Tribute with 94,000 miles had repeated check-engine issues after oxygen sensors and an EGR sensor were replaced. The EGR valve developed a hole twice, the engine idles poorly, is hard to keep running in the morning, loses power on hills, stalls when stopped, smells of fumes, and sometimes whistles on acceleration. Experts advised checking exhaust backpressure for a restricted catalytic converter, noting that a leaking EGR can cause idle and starting problems, and checking the IAC motor for sticking open.
