Car starts fine and when warmed up runs like a champ. However, when first started she doesn't want to hold idle and driving is very difficult even after a 5 minute warm up. Is there a FI adjustment or is this a timing or points issue?
Thanks, Ned |

Pulled the AAR - can blow air through it.
While the car was running I pulled the hose off the top of the pressure regulator and the idle picked up and the car ran perfectly. Is this a sign of an issue? |

Post a picture of what you are talking about because the only pressure regulator on a 2.0 is the fuel pressure regulator and the only hoses on that are fuel. If you are talking about the manifold pressure sensor, pulling the vaccum line off of that at idle would richen the mixture quite a bit. If that made it run better then check your head temp sensor resistance while cold and make sure you have the proper sensor for your ECU. |
