so I have this same exact issue, except its happening in my 96 pathy. Now I have had the issue for about 2 years now so the truck has pretty much sat. When it first started happening, I replaced the MAF and the problem went away for about a week then came back. Here's where it gets weird....if I push on the MAF sensor "plug" it gets better sometimes. I can be driving fine, then it will happen....then go away again. This happens all the time so I just stopped driving the truck. Think this fix could help me with my issue as well?
