what do i do?

just bought a STOCK BEAUTIFUL '72 1.7FI

always had carbs......it runs soooooooo smooth with the FI that im not ready to throw in the towel for my 40's...........yet, or should I?

it runs nice.....but i actually expected more power outta a porsche (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

my old bugs 1776cc had HELLA more headsnapping action....?? mebbe its the FI being weird? *crossing fingers*

it's mostly fine....but sometimes after coming off crusing speed for a bit, [5-10 min.....i live in WAY northern california, humboldt county, almost oregon, sea level, not to far to drive till i get to where im goin...so it never gets much workout...] it will stall out when it drops to idle.... then every time, till later after not being driven for a bit....the last few blocks home after getting off the highway is usually pretty aggro...

the other day tooling around Eureka, it was stalling out @ every red light & stop sign, i had to keep my foot on da gas to kep her from chokin out...

i bought a haynes mannual for my car already, but it says D-Jets you cant really do shit too.....so where am i left? i have nice carbs that can be dropped in an afternoon, but id like to rectify this insted if possible..

i ran 2 cans of chemtool injector cleaner through it with premium gas always [my old motor's builder said with the compression in it i should run hi-test]....should i run preimum in the 914 too? and it did feel better i think after those bottles of cleaner....

what now ?

thnks

Type I's are turboed like crazy....arent T4's? or is is a porsche engine bay space thing....? haynes says i need a CO monitor to tune the air/fuel ratio .... with only 87,xxx mi I dunno how the tranny could be so shitty felling....

turbos: it is a "there aren't enough T-IV people who want to pay the money to do it right to make it worth building a kit that people will bolt up to original engines and be pissed off when they break" thing.

a CO monitor is nice and not that expensive but if you fix and check all the stuff that can be done without it, you should find the CO will be correct. you cannot "just" tune the air/fuel ratio. you adjust the stuff like the fuel pressure regulator and make sure your manifold pressure sensor and cylinder head sensor are working. if they are - your mixture will be correct. if they're not, nothing you do will make it right...

your tranny can be shitty-shifting because the original 87,xxx mi rubber transmission and engine mounts and plastic shift linkage bushings are 35 years old and falling apart. your fuel lines are probably in the same shape, so be careful...
