Hi, the flexpipe on my 90 Maxima was partly broken but it ran fine. When it broke completly off it ran really rough. It seemed like after it got up to operating temp. Could this be messing with the sensors and effecting it when it goes into closed loop? The engine was shampooed recently but it ran fine it seems untill the pipe broke. What do you think the problem is? Also how much are WSP Y Pipes.

 

Um, a major component of your exhaust system breaks off, logic would dictate that it would affect how the engine runs and performs.

For Y pipe prices, just dig around. It's been mentioned about 3-4 times in the last week.

 

The exhaust is fixed now and it still does it. Could it be the coil or an ignition problem? Thanks.

i would say possibly your O2 sensor but it could be ignition or a fuel injector too
