Hi all, first of all i would like to say that before making this thread i dedicated many hours of research. I am aware of the common problems these cars have and what owners across the board are doing to solve such issues. I didnt however find a problem that best resembles what i'm experiencing here.
This is a 2003.5 Mazdaspeed protege that i purchased from the original owner, it has 161,000 miles on the clock and runs fairly well.
Upon purchasing the vehicle it had two codes, if i remember right they were p0171 and p0660 (not 100% sure). after inspecting the car i found the VICS solenoid valve defective, bad wastegate actuator, three huge cracks on the exhaust manifold, destroyed motor mounts, cracked intercooler hoses and a cracked radiator.
I purchased a steedspeed factory replacement manifold from another member, bought protegegarage poly motor mounts, brand new wastegate actuator, brand new radiator and corksport silicone intercooler hoses. I also checked with the dealer for possible re-calls and re-flash, they said everything seemed in order. i also checked for vacuum leaks.
After installing said parts the check engine light came off but the car does not run how its supposed to. The car will run great for the first 5 minutes of driving or when only at 1/2 throttle, other than that the car hesitates at around 3k RPM's when boost is supposed to kick in, does not accelerate much and boost dosnt seem to kick in till 5k rpm's.
The only other problem which i dont know if its associated is the smog, it failed but not too bad, attatched is a picture of the results.
if anyone car shine some light on this as i am running out of ideas and been searching like crazy almost day and night. I've replaced and fixed almost every problem i have found and i frankly dont see anything else wrong and there are no codes being thrown. I also need advice as to why I'm not passing smog.
thanks in advance guys
