1998 mustang gt 4.6L SOHC
MODS:
-sr lowering springs
-Summit aluminum upper intake manifold(non PI)
-Airtex fuel pump
-Recently replaced idle air control valve and MAF sensor. And all 02 sensors
Throwing code for: all o2 sensors(recently replaced) my car is now having excessive fuel pressure. Supposed to be like 32-36 psi at idle and is running 100psi. The only conclusion I can come to is the fuel pressure regulator however my local ford dealership says the fuel pressure regulator is fine but has the wrong rail on it??? They checked my vaccum lines, and fuel injectors. Everything seems to be fine. My question is if they are saying the regulator is fine but the fuel rail is bad. Is that the fix??? Apparently my car has the fuel pressure regulator built onto the fuel rails. But I have a return line style. All fuel lines were soaked and blew out to clear any blockage still nothing. Right now I'm debating. Should I buy a new fuel rail kit? I found one for $260 that included the regulator. Should I get it? I'm tired of throwing money into it and I'm trying to sell it. I have a family on the way. I'm trying to get out as cheap as possible but IdK what to do. I'm getting mixed answers because apparently they don't know ford did the split year on the fuel systems. 96-97 rails and 98 rails. The fuel rails have been brazed and replaced like the recalls said. But I guess my question is, is my regulator really bad or good? They told me just because it reads good doesn't mean its the right part????? IdK what my next step should be. Why is my car running so high. It starts fine it just bucks badly almost as if it were a miss fire. Due to excessive fuel pressure I'm guessing. What should I do??
