HI EVERYONE I RECENTLY REPLACED ALL SIX FUEL INJECTORS AND CAR RUNS GREAT WITH COLD MOTOR BUT AS IT WARMS UP I LOSE POWER AND ACCELERATION. I PUT ECU IN MODE THREE AND GOT CODE 13(ENGINE COOLANT TEMP. SENSOR). I WENT TO THE LOCAL PARTS STORE TO BUY A NEW SENSOR IN HOPES THAT I HAD FINALLY GOT EVERYTHING FIXED. AFTER INSTALLING NEW SENSOR I HAD NO CHANGE, ECU STILL GIVES ME CODE 13 AND NO PERFORMANCE CHANGE. PLEASE HELP I LOVE THIS CAR BUT ITS DRIVING ME CRAZY!!!!

 

We have two coolant sensors. One for the gauge, and one for the ECU Which one did you replace?

 

I REPLACED THE ONE WITH THE TWO 1/8" CONNECTORS, THE ONE TOWARDS THE BACK OF THE MOTOR. THE ECU IF IM NOT MISTAKEN.

 

Test the circuit (wiring and connector) for resistance. Did you perform any work in your engine compartment?
