hey guys, hows it going? just thought i would post up to see if anyone has experienced this problem or better yet knows how to fix it!!
the short story, i have had my 280zx off the road for about 4 or 5 weeks i guess, i put new extractors on, changed diff mount, fluid change all round etc, but because i put on new extractors i had to get the extractors welded to the existing exhaust...
so this morning the drive to the exhaust shop was very loud one. i picked up the car about a hour ago and everything sounded great and felt really good. so i thought after being so long i might put my foot down alittle. i got out onto the highway, put my foot down from a stop and it quickly climbed to around 3k then all of a sudden CUT no more power. i immediately pulled over because i thought something had gone horribly wrong but after checking everything then checking everything again it all looked fine :| the car idles fine, revs fine and freely in neutral but if your putting it under load it will cut between 2800-3200, and its a very severe cut.. im assuming its a fuel related issue but the only thing i did to the fuel system was install a new fuel filter and replace the old engine bay rubber fuel lines ( and they are connected correctly). I tried it a second time to see if it was just a one off and it happened again but I kept the foot down and it was almost like a violent rev limiter for 3k, it would build, cut, drop, build, cut, drop etc.
i found that you can reach any amount of revs you want if you baby it and climb the tacho slowly, it revs very freely and fast in neutral but once you select a gear and boot it (any gear) it just dosnt want to, this problem just occurs :S
iv never had this problem before and its a big tease not to mention very worrying. any help would be fantastic as im keen to sort this out ASAP
thanks for looking
