I have a miss at low rpm, seems to be at @2,000 rpms. I have had a new fuel pump, new fuel filter and had the fuel injectin system cleaned.It does seem to idle a bit rougher also.Could it be the TPS ?

Check for codes
and also pending codes
Check for vacuum leaks
Very uncommon for TPS to cause a misfire
Check it for tune up
Check coil and check distributor cap

I think I should add, the miss is random, and seems to almost go away after thorough warm up..I am replacing cap, rotor, plugs and wires today..The fact it almost always goes away after warm up has me baffled ??

Also no codes,
