The previous owner might have gotten rid of the tube and plugged it up, and the plug blew out (20psi of boost). Seems to run fine w/o it just loud as hell exhaust and crap for boost because the exhaus...

I have no idea, is the EGR in the side of the exhaust manifold? If it is the EGR then it really doesn't matter if i don't have it connected, right? I can just plug that to get rid of my exhaust leak a...

Oh btw if you didn't notice it under subject, the car is a merkur xr4ti, 1988.

The shop manual calls it a fitting and lists it as number 9F485, but what is it? It screws into the left side of the exhaust manifold and im guessing that a sensor goes into it? What sensor is it, can...

This guy did the volvo 16v swap on a merkur motor thats sitting in a foxbody mustang. Pretty cool site of the buildup, but here's the specific link to the head page. http://msvorinich.itgo.com/Octob...

Still haven't found the problem, could it be the fuel pump going bad? I started it up the other day and it ran real badly for the first minute, died once, turned back on no problems. After it warmed u...

Stock fuel pump, haven't touched the filter. I'll check the IAC, TPS, and the vacuum lines as soon as I can.

First thing is the boost, she boosts perfect up to 15 psi, then if i hammer it down I get crappy boost, like some air is leaking, irregular jerking motion. Quite annoying :( Can't find an air leak, ...

Ok, it goes at about the border of the rich at WOT, also turnes the color green so im betting thats good.(lol) Just wasn't sure what the difference for idle should be. Just something I noticed. First ...

It's an autometer gauge, doens't give numbers, lights up at a part of the uh, crescent i guess? It's not all the way to lean, and its constant, but its not where it is when WOT, should it differ at id...

To clarify, it runs a little toward the lean side when idling. I think thats normal, but you tell me, i'm not quite sure.

*new to turbo question* Is it normal to run bad A/F when idling? At WOT my A/F is good but at idle it is not.

I'm considering the FMIC and a rotated upper from bobs so its facing the intercooler and doesn't have to hit a 90 degree turn. Also considered a new header and upgrade to a 3" downpipe. Beyond mods li...

She's in the mid 13's right now, or at least thats what I understand from who I bought it from, off this site actually :p My goal is to have it into the 12's, mid 12's maybe. Not looking to drop a t...

I'm not the most knowledgeable about cars, so help me out will ya :p 1988 Merkur Xr4ti- At the moment I have a TC top mounted intercooler. Now this type of intercooler has reduced turbo lag but its...

Ignition module, thanks! That's something I can replace myself.

The mustang finally seems to be dying on me. First it started with my tach not reading right, it would be fine and then it would dip down to bout 1/3 what it should be reading, then come back. Pretty ...

Got her done, runs fine, no more air leak. Be awhile till I consider porting the lower intake manifold, which will be the one that gives me actual gain, :p

Well I found where the leak was, took me 20 minutes to fix it and be off. Car was at my buddy's so had to have him give me a ride there before he went to work, if I couldn't have fixed it I would have...

If this is my PCV valve then I do have both those hoses hooked up to it. [link]http://www.internationalfilters.com/products/pcv.jpg[/link]
