Hesitation
 

Hey guys. Currently having trouble with my 86 z31. pulled the following codes from the ecu 13, 14, 21, 23, 24 & 31 which is fine. Experiencing bogging at low rpms and runs like a champ when i gun the hoe through +2700 rpms. has decent idle but not perfect. spark plugs are in good shape, just pulled the injectors and saw that the screens were clean. no vacuum leaks and the bitch is in time. If anyone has any clue to anything i can do PLEASE HELP!!! :confused: i miss showing my two girls off in the city of Austin TX and going on long drives where i'm not embaressed with how i can't get my car to run right. Any direction would be MUCH appreciated. :icon_oak:

Not entirely sure, but I would check out the MAF. I've had an issue like that with my 88, and replacing the MAF worked. Just unplug it and see if it idles good. You won't really be able to test it too much because that will send it into limp-mode, and it won't rev over 2000. Hope this helps.
