Good day,
I have an 89 240 DL LH2.4 with aprox 245k miles with a good ole m47 transmission. She is most happy when its a nice sunny and 75 degree day (but who isn't??? ) On the other hand She is not so happy when the temperature dips into the 30's on my morning commute into work.
She fires right up every time and after a few minuets of gathering her bearings, has a nice and smooth idle. Its honestly pretty impressive. Typically when it is cold out in the 30's or so I let her warm up for about 5-10 min before I hit the road. This is about the time my my issue starts. I will do the best to describe it... It feels and sounds as if the motor is "stuffed up" she revs differently shifting through gears and kind of sounds bogged down, almost like the exhaust is trying to be passed through a pinhole. It just feels/sounds completely different than when the weather is warmer out.
I have replaced a few items all within the year that include new spark plugs (bosch coppers) spark plug wires, distributor cap and rotor as well as a new 02 sensor, ECT Sensor, MAF, air filter and have replaced pink label ECU with one from a 93. I have also cleaned the flame trap and currently running 10w30 oil.
No codes are being thrown and I do not have a CEL on the dash.
I am trying to see if anyone has experienced this with their red blocks or if its simply the temperament of an older engine. She is a bit slap happy when cold but hell I have very rarely met a 240 without piston slap.
The last thing I can think of is replacing the thermostat.
Thanks!
