Newbie FI issue, Idles but does not want to rev up Options

[thewheel69]

Hi Folks, I just received delivery of my first fuel injected 1.8 (I have owned 4 other 914's but all of them were already converted to carb)

This little honey is a 1.8 nearly rust free CA car with great potential for a rolling restoration.

When I got her, she fired right up but would never get past that in revs... it would start backfiring and then die. after letting it warm up a bit, she all of a sudden she just perked right up and ran like she should, reving up and very peppy. I drove her around the block and was delighted that she shifted fine and brought me much joy which was temporary... as I turned a corner, she started sputtering again and died. She started back up and I coexed her home but she has never been the same since.

I took the fuel pump out to check its operation, made sure the fuel filter was not plugged with debris and shook all the various wires and hoses to ensure proper connection, etc.

I have only about 1/4 tank of fuel to which I added some SeaFoam and dry gas.

I checked the distributor for loose connections and condensation.

I am working a bit blind as I do not have a shop manual (on order) but am optimistic that I am just being a dumbass and not doing/checking something in the proper order.

Help! and Thanks in advance!
