Hey what's up guys,
I'm hoping someone can help me with this. I have a automatic 1991 300zx Twin Turbo. Yesterday I was driving on the freeway going about 65mph. I punched it, picked up boost and got up to about 90mph. I held it at 90mph for about 10 secs. Right after I let off the throttle, my HICAS light, E brake light, and rear brake light indicator came on and stayed on. I also noticed that the stock boost gage stopped working. I checked my power steering and brake fluid levels and both were fine. I changed my brake pads about 2 months ago. I've checked various fuses and all are fine. I put the car on a scanner and it came up with a 03 tranny code which has something to do with the TPS I believe. Could this be affecting it? The car is not misfiring and still has a lot of power. I can still feel the boost. My car is pretty much stock. I've only changed the exhaust, added a JWT Pop charger, and added blow off valves. The mods were done almost a year ago. I've never had a problem with the car. Any input with be greatly appreciated. Thanks
