samisunjp Posted July 11, 2017 Share Posted July 11, 2017 I have a '94 loyale 5 speed spfi. Just re-did all of the seals on the engine and have her back in and hooked all up. Starting her up is a little rough but I can get her to stay running. The idle is low and when you step on the gas pedal it will either stall out or sputter and then start to steadily increase rpm but be very hesitant and not keep constant power. also will backfire once and a while when you step on it before the rpm's drop. I checked the TPS and it is within spec and the water temperature sender seems to be doing its job as well. Sprayed carb cleaner to check for vacuum leaks and didn't find any. Fuel filter is brand new. I appreciate any help or input that I can get! Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 11, 2017 Share Posted July 11, 2017 These are two coolant temp sensors. Which one "seems" fine and how did you come to this conclusion. The dash gauge does not use the sensor the fuel injection uses. GD Quote Link to comment Share on other sites More sharing options...
samisunjp Posted July 11, 2017 Author Share Posted July 11, 2017 I pulled the one closest to the thermostat housing ( green pig tail connector) and checked the resistance with my multi-meter and some boiling water and the resistance seemed to change within spec as it heated and cooled.

Gloyale Posted July 11, 2017 Share Posted July 11, 2017 set the ignition timing? Checked all PCV and IAC and Vac hoses? Quote Link to comment Share on other sites More sharing options...
samisunjp Posted July 11, 2017 Author Share Posted July 11, 2017 Pcv are brand new and iac are clear. Ill check timing but, would that cause the stalling? Quote Link to comment Share on other sites More sharing options...
DaveT Posted July 11, 2017 Share Posted July 11, 2017 The idle as control solenoid - if the coil is open, it will die when you let the throttle fully close. As if you shut it off. Quote Link to comment Share on other sites More sharing options...
Dee2 Posted July 11, 2017 Share Posted July 11, 2017 backfiring can be a strong indicator of a timing problem. Stick a vacuum gauge on it and see what it tells you. Quote Link to comment Share on other sites More sharing options...
