ok here is what i have... 94 del sol with a ls/vtec swap... the car ran fine until it started to get really cold here... now the car will start up just fine when cold run till it warms up then bog out and die... after that it will just sit there and crank and every now and then backfire....

here is what ive done so far
put in new MSD Street Fire Ignition
new MSD Blaster SS Ignition Coil
new MSD Modified Distributor Cap & Rotor Kit
new main relay
new spark plugs
(wires are not very old and still in good shape)

i know that all the wiring is done right because the car fired right up while cold with all the new parts on it... but after it warmed up same problem...

i could really use some help... i cant keep throwing money at the car hoping to hit the right problem

Maybe ur gas pump might be goin bad, when it gets to a hot temp it gives out u should check that.imo

try your ignition module. they have a grease that goes underneath them. once that grease breaks down they start heating up and once they are hot they will not work correctly. once it cools down it will work fine. sounds to me like that is your issue. you can have it tested at most auto parts retailers. you will need to remove it from the vehicle first.

I believe that is heat transfer paste you are referring to. Another name might be thermal paste. You will probably have to pick it up at Radio Shack. Not sure if Autozone or Advance type stores will have it.

i will pull the ignition module of tomorrow when i get up... is there a way i can test it myself? i dont think the small town napa here will test it for me... and u think its bad or that i just need to put more of that thermal paste down?
thanks for the help so far

Try cleaning the IACV. Also check the cap and rotor and the ignition timing.
