rich17 Posted March 27, 2012 Report Share Posted March 27, 2012 Welp my elderly neighbor boght this thing brand new. Mustve been one of the first with a build date of 6/94. Its a Z35 but even has drums.. BEen having intermittent surging problems. I did the ole carb clean spray and found the egr gaskets were leaking. So yesterday i did them, the upper, and both VC's. But still has the problem. No codes pop up either. Someone suggested TPS but without the SES light being on I am a little hesitant. Any suggestions other than swapping in a 3800? lol Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted March 27, 2012 Report Share Posted March 27, 2012 surging could be from the MAF or IAC acting up. Quote Link to comment Share on other sites More sharing options...
95 vert Posted March 27, 2012 Report Share Posted March 27, 2012 Lower intake leak Quote Link to comment Share on other sites More sharing options...
3pt1lumina Posted March 27, 2012 Report Share Posted March 27, 2012 Lower intake leak X2, just went through this with my dad's 95 LQ1 in his Z34. Replaced the IAC/TPS and checked all vacuum. Then the car started leaking coolant from the lower intakes and then it became real obvious what the issue was. Replaced and now it runs mint.

RobertISaar Posted March 27, 2012 Report Share Posted March 27, 2012 all 95 Z34s had drums. 96 is when disks started coming into the 1.5s. Quote Link to comment Share on other sites More sharing options...
