I have a 96 max thats supercharged. My problem is that the stillen fuel set-up I have vs. code that came up at nissan. The other day I changed my plugs and shortly after that my check engine light came on. I went to get it checked out this morning and they came up with a code that the TPS censor was bad. Now I had replaced the Hobs vacum switch since I thought that was a bad switch. After changing that switch the problem still occured.

The problem is that the car is bucking or hesitating before it takes off like its either not getting enough fuel due to something wrong in the fuel system or because of this TPS switch. I was told by a few people including the people at nissan that this could be the reason my car is bucking/hesitating. The check engine light hasnt come back on since 3pm today when the code was cleared. Now a tech friend of mine said that the light would come right back on if the TPS censor was bad but it hasnt. Can someone please help me out with this if this has happened to anyone or just throw out some idea's on what this problem might be.

p.s. this problem happened right after the SC was installed. thinking it was this hobs switch which was replaced the problem still occured, could this be the TPS censor?

thanks

Do yourself a favor and disconnect the vacuum line to the Hobbs switch and plug up vacuum source... Keep it running full time... Clear out the ECU to relearn... If you don't mind the little extra noise, you'll be much happier with it.

 

that sounds like a good idea, I will try it out.


engine light hasnt gone back on so I imagine the TPS censor was never broken
