Volvo: air/gas mix??, rotor wire, temp gauge

Question
Hey Vedat,

glad to read about your experience....I most definitely need your help. I own a 1980 240, B21 engine if I'm right. My father bought this brand new, and just gave it to me as a birthday present. As a matter of fact, this is the 4th Volvo I own...all 1985 and older!

Ok, this baby looks very good, but she's giving me a headache on a daily basis. Whenever I start her, I always wait to have the temp gauge move a bit...I mean she's old! For the first 15-20 minutes that I roll with her, she sounds really weird...and feels really weird at low RPM (less then 3000rpm). It feels like she's 'coughing'? Really feels like there's too much gas for the air intake? I mean, I might be completely wrong...it's just the way it feels. Carb issue? Fuel pump? Fuel filter? Would a good check up, replacing plugs, rotor, wire, ect help? May I mention that she also smells gas....fresh gas as a matter of fact...not burnt. THen, when I've been going around town for 25-30 minutes or more, she feels perfect...

Anyways, I'd really love to take care of this, as everything else is good on this car...

Feel free to ask me questions to help you figure it out..

Thanks for your time...and Volvo rules!!!

Dave

Answer
Hello,
according to your clues, the car is good when it is hot, the problem occures when it is cold.
So, firstly the problem cause can be ECT Engine Cooling Temperature sensor...Try the car with a new ECT sensor.
Secondly, the fuel pump! But first ECT sensor...
