Wifes car has a problem! Any ideas? I'm all out!

The link takes me to a page where I have to register. Must have to be a member to see what your linking to. That is ok though, I found it!
Changed it out and took a drive. About 60 miles. No problems. That isn’t a for sure thing though since it has gone that far before without anything happening. Only time will tell.
Thanks for all your guys help! We’ll keep our fingers crossed!

If its the P0507, you should notice a high idle as well. It will idle around 950 or higher instead of the normal 750. The vacuum leak will be around the #1 cylinder, that’s the one closest to the passenger side. Its easy to check, with the engine idling, spray some carburetor cleaner or spray oil (wd40) all around the edge of the gasket, the idle will change when you spray near the leak.

I hate to be a guesser, but back when I used to turn a wrench (1980s!)Fords used to do that all the time. Later model Hondas too (not as many as the Fords). Dealers used to replace entire fuel systems, and do valve jobs, etc. The real culprit 9 out of 10 times would be the igniton module or a related primary ignition circuit such as the speed sensor on the distributor. We didn’t have the tools to diagnose correctly because there was no standardization then, so we kept a good assortment of good ignition modules around. If you’re a do it yourselfer, find out where the engine speed sensor is (probably on the bottom of the distributor) and the ignition module (it probably has a different name now), strip them out of a car at the junkyard and put em in your car - you’re using these junk parts as a diagnostic tool only. If that changes the problem, go to NAPA and get new ones. If it is ot the problem, you still spent less money than an hour at the mechanic

That’s good about changing the fuel pump relay: but, I’d still like to change the fuel filter/regulator. They probably are original, and this is one of those times when original isn’t good.

I tried getting on that recently and discovered that they’ve made some changes. They seem to no longer offer the level of information they did, no more “exploded view drawings”. They must have realized it was cutting into their sales of repair manuals, which you can conveiently buy through that same site.
