so i picked up this little 92 pickup with a 22re anyways it ran really bad .
i found the air flow meter was bad/replaced it. but now it seems like it only runs on 2 cylinders #2 and 3. while it was running i pulled the plug wires off 1 and 4 and there was no change in the way it ran. but if i pull them off 1 0r 3 the engine dies. i checked spark and it looks good. when i pulled the plugs 2 and 3 looked normal like they were firing but 1 and 4 look carbon fouled im thnkin for some reason those injectors arent working. if anyone could help me out here id appreciate it thanks>

 

Kinda sounds like it. The only way to really know for sure is to test them. You could try running some cleaner through first and see if that helps.
