my buddy and I decided to install my HO upper on his SO 5.0 the install went well but now the car runs rich is there something we need to know about the swap or are they not compatible? his car is a bone stock 88 LX.
Shouldn't make it run any different. Check for vac leaks. Especially the one running to the fuel reg.
I forgot to add that he has an adjustable fuel regulator and 19# injectors and the stock computer, now where should the fuel pressure be set? it was at about 55#'s while the engine was running and I tuned it down to about 35#'s is this too low? should we swap the stock injectors back in?
the 19's will make it run rich been there done that got the T shirt
put in the stockers back in and the problem will be gone.
fuel pressure needs to be 39 psi with the vac line disconnected
will a cam upgrade help or do you haveto go ho on the comp too?
The computer won't deal with 19lb injectors without a tune. That thing must just be dumping fuel.
Cam needs different firing order EEC and the EEC needs to be swapped for any other injector.
19#'s with stock SO computer LOL been there done that.. you'll need a gas station before you get a post on this thread.. I went through a crazy amount of gas in the little 30-40 mile trip I went on with it
just entering this thread dropped my I.Q. point. well done!
dont come in here to hate... V8 EFI is new to me and I'm not here for ignorant comments.. here to learn so keep your comments to yourself if you dont have something to say to help someone in need. By the way the problem is solved and I knew that you dont mix 19# injectors and a stock computer. Mods please lock this thread!
i had that same screwed up setup when i got my car and it stayed that way until about a month ago...
HO upper, 19# injectors, stock computer.....
the stock computer DEFINATELY doesnt like bigger injectors. i put a B cam and SD HO computer in it and it runs 200% better.
you knew, but still had to ask why it was running rich? riiiiight.
With 3200+ posts you ain't exactly a newbie, what you were doing had been tried unsuccessfully several times before... Should have at least known all Ford EFI & SEFI systems run 39PSI F/P...
Unless the asthmatic stock 50mm throttle body was also upgraded, the HO intake nets ZERO gain on a SO 5.0...
I did say this is my buddies car NOT mine and I did NOT put the 19#ers in and for everyones info somewhere along the line we knocked the vacuum off the map sensor causing it to run rich. theres no need to treat me like im stupid. and tom I wasn't aware of the 39# setting. and to 32v sometimes I like a second opinion so I can check my work. we did swap it back to the stock injectors like I was trying to explain to my buddy. to the ones that did help Thank You.
I changed my user title for you and everyone else. :)

And when push comes to shove on some of the earlier stuff on the site before the great crash of 2007, You can go to google and type "site:www.foxtbirdcougarforums.com" with no spaces and then put a space and search for the term you are looking for. It will give you every instance of said term within the site
Example:
Typing -- site:http://www.foxtbirdcougarforums.com supercharger
gives you: http://www.google.com/search?hl=en&q=site%3Awww.foxtbirdcougarforums.com+supercharger&cts=1255108942896&aq=f&oq=&aqi=
While I'm sure you know where the search function is I had meant to point out that pehaps a more thorough use of the advanced functions was in order. No insult was intended.
thanks Paul I'm sorry
No worries ;)
The context gets lost when you read it and can't hear the words on occasion.
