I have a 90 integra having problems with starting when hot. If it starts it will run good except for below 2000 rpm when pulling off from dead stop. It will spudder and the clear up at about 2000. I have already replaced the main relay and the spark plugs. Should injector cleaner be my next move?

sounds like your timing may be off. check timing, and make sure that your timing belt is properly oriented between the crank and cam gears.

OR

Your valves are out of adjustment

Cap, rotor and wires are your next move, does the idle change when you squeeze the fuel pressure regulator vacuum hose.

Need some more symptoms for further help .

The TITLE of your post and the description are to different problems, no start hot is a bad ECT (TW) sensor, its a long story, I just did a post on this somewhere in the last few days but, once warm, the TW sensor no longer comes into play with the computer, if it goes bad (glitches) you wont know it until you do a restart hot.
