If it is fuel injected (BTW I have a 72 1.7L in a 74 that had a 1.8L L-jet hacked to a 32/36 single carb) and it happened right after the filter change make sure of the following.

1. That the fuel pressure regulator is hooked up right. I don't even know if the car will run with it backwards but check it anyway. Look up Dave Darling's hose diagram in the tech ref section.

2. Make sure the fuel filter is in right, it should have a flow direction arrow.

3. Make sure you didn't inadvertantly unplug the MPS vac line. My 1.7L ran like a dog until WOT then it was great. The problem is with no vac signal the MPS assume you are at WOT all the time.

4. You are useing the 1.7L MPS, right? If you try the 2.0L it will make the engine run very iregularly BTDT.

5. Make sure the Cylider Head Temp sender didn't get unpluged.

6. If you are using carbs...you are on your own.
