93 ka24de engine problem!

[93SECOUPEsx]

Hey Nico club,
I have a 1993 Nissan 240sx SE coupe and I'm having a problem with the engine.. It keeps flooding every time it is being started and when ran.. this has been going on for about a month since I replaced the intake manifold gasket..

Things done to car/CAR SPECSREBUILT Ka24de, xxr wheels, skunk2 racing springs(3in lower), drilled and slotted front rotors infiniti q45 set up (stock rear brake set up), 3in (unknown) brand catback exhaust, 10k HID, pioneer stereo wired for subs, HUD, 200k+ On body,everything else pretty stock.

History that lead up to this problem: Anyways, car was having an idle problem.. Checked for vacuum lines couldn't seem to find any leaks. Decided to go ahead and replace iacv instead of cleaning it. Fired it up still had CRAZY rediculious idle. Up and down idle 900k-1800k rpm. Listened around.. Noticed intake manifold gasket was mangled and tore and hissing it was just a mess... Took the whole intake side apart( fuel rail, injectors, lines, egr, bpt, fpr, etc) and replaced intake manifold gasket.. Next day fired up car and it had REALLY odd sputtering, idling, and the engine flooded... Well, took ECU out and turned the screw and it gave me a code 34.. Which is the knock sensor.. So I ordered knock sensor from frsport.com and ordered a new knock sensor sub harness from wiring specialties... Got that shipped out to me put it on and fired her up.. Thing wouldn't even start.. It turned over but didn't start... Charged battery and tried again.. Didn't start.. Pumped the gas while turning it over and it fired up.. But then got flooded again. Pulled spark plugs cylinder 1,3,4 were black.. Cylinder 2 was wet with gas.. (NOW THESE ARE BRAND NEW) ngk iridium ix spark plugs.. Anyways but this flooding and everything with the car running really rich and weird started after I did the intake manifold gasket... ANY SUGGESTIONS??? In need of help ASAP! Thanks to all who have read.. I appreciate any replies and suggestions.. And just to let everyone know who reads this.. I'm new to forum! My names Cody

One of the things a lot of people do including myself and other friends was to be sure your spark plug wires are in the right firing order. Been awhile since I played with a KA.

What Lobo said. I bought a 240 with a "blown" engine once that turned out to be mixed up plug wires It sort of sounds like you might have an injector sticking on cylinder 2. Not sure what would be causing the rest of them to rich out. All the grounds near the injectors clean/tight?
