There was old gas in it but we got rid of it and put fresh in there. Its been running on fresh gas for quite a while now. I'll have to check the fuel pressure but I don't think the pump is the problem.
For some reason I feel I might have been describing my problem incorrectly. So I will retype it to make sure I didn't confuse anyone along the way.
On my way home just a little bit ago. I took off from a light keeping a level amount of pressure on the gas. Not too much as I am a slow driving of sorts and baby my vehicles. When it would randomly act like it either wasn't getting enough gas or air, spitting and spuddering and having no power. So I have to push harder on the gas until it stops and begins running properly. Then I can reduce the amount of pressure back to what I usually drive at. Again this doesn't happen all the time, just when it feels like. When we advanced the timing the most of the problem went away, but it would lightly act up from time to time. There is still the miss with or without the timing advanced its just less noticable when you advance it.
Hopefully that should straighten things out a bit. Sometimes I don't check over what I post and just wanted to clear up and confusion if it exists.
Just got back inside. All the wires going to the MAP sensor look fine, as do all the other wires I could see under the hood. Tried hooking up the EGR valve and it runs pretty bad with the vacuum hooked up. But with it unhooked it runs a lot better. Unplugged the TPS and the motor revs so that seems like it works..but haven't checked if it is within parameters. Now I remember posting this before but I'll do it again. When I unplug the IAC, nothing happens. Not sure if its suppose to do that or not.
I tried running codes again the other day and I got 22 again. Even though I just replaced it. As for the vacuum lines, no the one leading EGR plate is not blocked off. The vacuum diagram is missing from my car, are there any other lines I might have missed that go to the EGR valve. Again not my doing my father was the one that did it even though I told him to hook it up. But he did mention when the EGR valve was hooked up that it ran worse? Possibly clogged you think?
EGR is actually not hooked up. It was my fathers doing, not my choice. I think the only thing not hooked up is the vacuum line going to the top of it. All the electrics are plugged in. I've been wondering if that was going to cause a problem.
Ok I'm bring this thread back ya'll. After driving that car around for a while with the timing advanced a bit, it did run better but still occasionally misses. We had some last minute adjustments to the Cougar over the weekend and set the timing back a bit to get the idle down. Now the hesitation is back just like before, still coming and going as it pleases. Just took the time to triple check all of the vacuum lines and they are all great. Replaces the PCV valve and looked over my electrical connects. So as I stand...I'm stumped. I can't explain the miss or hesitation. Even if I advance the timing it will increase the idle but a slight miss still rears its ugly head. Any thoughts? Maybe a sticking fuel pressure regulator? another electrical problem perhaps?
Whoops made a mistake there, I meant I "had"a 78' XR7. I wish I still had pics of it. It was rust free...just like my current XR7. I've been getting pretty lucky with that recently.
Bah! :p That sucks, but its cool. Gotta appreciate those older Cougars as well. I have a 78' XR-7 in black with a 351w. They are very nice cars, I dig yours btw.
I'm gonna try my hand at painting a grill I got coming in, but I need some advice. It's a chrome grill and I want to paint it flat black. This isn't going to be anything perfect, just thought the black would look better on the front of my XR7. Any advice on the procedures and equipmend to use. Thanks again guys, I usually have my dad to help me with this but since I'm moving. Gonna start doing this stuff myself.
