repost..need feedback...

sup guys, my b18c1 was rebuilt a couple thousand miles ago....during break in the motor ran great....
i recently installed a 190 walbro pump and 310cc injectors ( in a eg chassis)...

after the install, or shortly thereafter, the car started to act up.
the idle holds fine..when it wants to...at 700-750 rpm...then sometimes in the 500 rpm range...
when i drive...and come to a stop...it dips in the 500 range as well...then struggles its way back up.

when i start her up...its not a crisp clean start up like usual...theres a bit of struggle there as well..

the motor is strong, did a compression ttest and the numbers are great.
the only thing(s) changes are the injectors and pump....i'm running a chipped p28 currently...

the research i have done is to check the 02, iac valve, clean and check t/b, air filter, plugs etc...
i'm wondering if i'm running way rich???
fpr reads at 42 psi at idle...

any info or feedback will be greatly appreciated...
thanks

 

Has the motor been tuned? I know my chipped p28 ran pig rich at idle.

 

i just installed the injectors to tune this week....but the tuner is booked til next thursday....almost 2 weeks...just wondering if my car is safe to drive...daily...til then
