Default 1991 leggy turbo hesitation

I have a 91ss 4eat that has hesitation above 3k rpm. I've done plugs, swapped wires, fuel filter, coil, knock sensor, you name it and I've probably messed with it. Anyone have similar issues? I have no cel. I'm gonna try to swap mafs this weekend.

I don't really have an answer for you. These cars can be tempermental. You may want to search/post on www.bbs.legacycentral.org if you haven't already done so.

Should work, like 5 bucks. Should be able to get it at AZ or Wal-mart. I've used it on both my Legacy and on the STi.

Default hesitation

Is the hesitation pre or post full warm? or is it in between the ECU going closed loop? this threshold would about 10-12 minutes after startup and drive away. My 93 4eat has this symptom and I think it is related to the O2 sensor. I have the ECU interface built that allows me to look at it real time via RS232 serial and a free Win32 application called SelectMonitor. Check the site http://www.vwrx.com/index.php?pg=selectmonitor. Code is based primarily from VRG3's (legacyCentral) work and effort. If you have questions, PM me and I might be able to help.
