Car: 1994 civic Si
Engine: 2001 USDM ITR

problem: checked plugs a couple weeks after changing them. plugs 1&2 had some kinda white build up on them. 3&4 looked normal. Car seems to run a little warm. The temp gauge gets up to the half way mark after driving it for 2 minutes and seems like it takes forever to cool down. Event he mechanic that did the valve adjustment and compression test commented on it taking soo long to cool down. For cooling Im running a FAL fan and a PWR civic radiator. Any guesses?

 

white build up is detonation. Are you getting enough fuel pressure and volume? Are the fuel injectors good for cyl. 1 and 2?

 

the white deposit on the spark plug is a cause of a lean condition you mithg want to chage or check the injectors & the running hot think you should check the egr valve and the heated valve. good lok

EGR valve? You realize this is an Integra motor we are talking about?


I would check your fuel supply (pump, lines, fuel pressure, injectors) Something is leaning out those two cylinders.

 

Must be the injectors I guess. I'm using the ITR fuel pump and a B&M FPR set to 39psi at idle. Should i just give it more fuel across the board? What else can I do to these 2 cylinders then?

 

Also would the detonation in these 2 cylinders make the temps that much hotter?
