New to ZR-1 Removed Sec Vac system and now problem

[illeagleracing]

Thank god I found this site a few weeks ago. I decided that the secondary vac system had to go so I ordered gaskets from jerry. Removed all vac junk under the plenum, pinned the secondaries open, replaced all nec vac lines, and installed chip from Haibeck. Started the car and it started up and fell down to idle and died. Check engine light is on now and car will idle sometimes but has a hesitation at idle. What should I check???? Again NO emissions/secondary junk is on the car but did leave everything connected electrically wise.

Only modifications are headers, full exhaust, no emissions and now Haibeck chip.

I did start the car without the map sensor plugged in had an oops moment wasn't sure if that has caused some code I need to dump or not

Any of you zr experts imput would be appreciated
