Thanks, that is a very nice resource. I found the part number for the wiring harness which is great. Is that cluster of hoses the vacuum manifold? Really I’m trying to identify the proper names of things so I can order the right parts. Thanks for all the help.

Yes that’s it. Should one of the caps be missing? My guess is no. So how do I know if tps is bad. I’m looking at it now, I’ve got 5 v from the computer but it’s send 1.5 back with closed throttle. Best I can do is 1.4 after adjusting the sensor. For a new sensor it sounds like that indicates a...

Time for amateur hour. Thats a good bit to digest but really helpful. Based on that I am going to start by soaking the IAB (can't hurt) and probe the TPS voltage, I'm suspicious that it will need to be replaced since its original. I'll also splice the fuel injector cable until I can get it...

I'm prepared for the public shaming but after neglecting my 1990 for the last few years I finally got a bug up my butt to get her back on the road. After spending some time this weekend and last I have her running though not very well. Today I pulled some codes and noted a few things about how...

I tried to hook up my battery charger this morning, thinking that I should let it charge during the day and I could try the rolling start test again this evening. When I went to hook it up, the charger immediately went into "fault" mode and would not charge the battery. Tonight I am going to...

So I have a '90 5.0 that for the last 3-5 months has sat without being driven or started. This weekend I tried to start her up but was unable to do so, even while doing a jump from my other car. When I try and crank the engine I get a clicking sound. When trying to start the car I see a high...

Would anyone have a picture of the EGR valve? Not sure if i am looking at the right thing over here. Could these two codes be in anyway related? A couple of weeks ago she was running fine, now she runs really rough, almost like it is missing. Funny thing is it only does it sometimes. On...

Last weekend I was pulling code 33 and 44, anyone have these or ideas what needs to be replaced? Thanks

Thanks for the post. I went ahead and ordered one of the Equus testers. I figured for 30 bucks, why not, atleast this way I dont have to translate flashes into numbers, plus i dont have a test light. I hope to have the device soon, with in the week. I will post the codes as soon as I can...

So Saturday night I drove my car all night with no problems. Sunday morning I come out and start up the stang and she starts doing this surging idle thing. I let it run for a couple of minutes and it gets no better. So I turn the car off and start it back up. The problem is completely gone...

Ok, so it sounds like getting a new temp gauge is the first step and possibly a new t-stat seems like the way to go. I will prob get the 180* stat anyway, since this weekend or the next I am going to drain the anti-freeze again and flush the system. When I drained the system to put the new...

So just a week or two ago I finished up installing my Upper and lower intake. Since then I have put about 200 miles on the car but it seems like its running alittle warmer then it used to. Once the car gets to operating temp it stays very steady at the half way point on the gauge. If I...

I was about to start the install on my CAI this afternoon, when I noticed that the pipe from the throttle body to the mass air flow sensor was really long. So long in fact that the only way I could put it on was if I relocated the MAF. My question is did anyone else have to relocate the MAF...

Thanks man, i figured it would be something like that, but I just needed to make sure.

I think its safe to say that if you put on the quads and the drag radials you could hit high 12's. The fiber hood, battery relocate and skinnies would help but I doupt it would be enough to really notice. With some good traction, you should be able to get off the line faster and improve you...

This may be a dumb question but I need know. So I was about to buy the FRPP unequal length headers, when I noticed it says "Not legal for sale or use on pollution-controlled motor vehicles.". I just wanted to know what is it that makes these headers non-legal. I have to pass emissions in...

I can not for the life of me find the four throttle body studs that connect the throttle body to upper intake. Mine are to rusted to salvage. I have looked on jegs, summit, and googled a million things. Can some please post a link to them. I have a 1990 5.0 lx, but just put the cobra intake...

I dont know, this is the first time i have done anything even closely related to this stuff. These are stock heads and stock rocker arms. Please explain the difference.

I searched and didnt really see anything that helps me. I was reading the hayes manual about installing the rocker arms and it says to rotate the cranksaft until the push rod is on the base of the camsaft (I am guessing this is the lowest point). How do I know when its on the base of the...

I knew that the lower wouldnt fit I was just concerned when i saw that the vacuume lines where not the same.
