When I excellerate for example from 2nd to third the engine seems to cut out and then dies. I thought it was an electrical problem or the FP relay; I cleaned the relay board throughly as suggested by the fourm and also installed new relays. Today I drove the car down the street and it died again and the same thing happened. When the car came to rest I turned the key, the FP ran and the car start and I drove it home in a slow 2nd gear. Any one have a glue? maybe some valve or elect. sending unit of some kind. Any suggestion would help. Mike

Hows your fuel filter?

Start the car and let idle. Gently press on the gas pedal until the engine is nearing red-line. If you can't get the gas pedal to the 1/2 way point without the engine dieing/dropping rpm then the advance mechanisim is failing or your FI trigger points are bad.

The only reason I know this is that it happened to a curstomer's car recently. I swapped out the dizzy and the engine was fine after that

Naturally, it is assumed the valves are adjusted, the dizzy points are properly set and working, and the spark plugs are gapped and have good wires

What year and injection system?

Check for vacuum leaks?

I will try all of your suggestions, The injection I beleive it's the original and the fuel filter is about six months old with only about 1000 mi, but the gas could be dirty.
I did have an electronic ignition installed about 2 month ago???

Thanks everyone, this is a great site Mike

Okay, what year is your car and what displacement is it?

If you say 'stock injection system' it could be two different kinds. You gotta be specific as they measure air and meter fuel differently.

Yes, sorry I should have been more spacific. The car is a 1973 1.7 Fuel Injected all original except the electronic ignition. Thanks for your help I am completely frustrated by it. This time of the year in the Houston area is the best time to have this car on the road. Mike

Here are a few possibilities:

Vacuum leaks (check all of your rubber lines).

Manifold Pressure Sensor failing.

Distributor components might be failing (Points, condensor, trigger points, vacuum advance pot).

How can I get my car to excellerate?--It's real good (the 914s all were good--its the mid-engine design), but it doesn't excel--has a few rust spots, and runs rough when cold. Maybe to excellerate, I need to put a 6 in--even conversions are pricey--must be excel-lent.

accelerate = to move or go faster; increase in speed.
Also accel. (abbreviation); acceleration
excellerate = not a real word.
