I am having problems with my sr20det, it started with back pressure cause of the cat and jdm stock exhaust the manifold and turbo was getting hot and the car kept dying when it came to stops, the voltage kept droping . I have bought a test pipe and and a tanabe 3 inch catback and now I don't feel it getting as hot as before so I guess the back pressure is gone but when I do drive it voltage drop a lil and it dies at 4 out 5 stops and when I go it seems boost lag more than usual. I think I burn'd my air flow sensor but really not sure or some kind of burn'd sensor or something. Anyone every counter something like this please help me in cause it is driving me crazy cause this is my daily driver, I drive to work and I do like 4 or 5 delivers a day for supplies and across the city and it keeps dying it gets my so frustrated, please help anybody know what it can be ????? Thanks

 

check for any boost leaks....i know a sr will run like poop with a boost leak. MAF would be a good thing to replace as well.\
good luck

 

Thanks I will try tomorrow, I am trying 2 fix my problem so I can drift in an upcoming event on the 19th here at portland raceway.

 

Is the ECU throwing any codes? Look to see if the LED is glowing, if so, it has error codes waiting to be read.

 

Problem still not solve, sometime I drive I get back fire, even at low speeds?????????????????
Help anyone that had this problem, anything to make this run right! I think it has a leak in the pipings?
