Update Long story short I had to replace the coolant temperature sensor with a Bosch coolant sensor and I ran some sea foam in the crankcase fuel and vacuum lines And my codes cleared and stayed cleared car is starting up a lot better and running good! Previous coolant temp sensor was purchased thro...

Sounds about right to me. I can get the meter this weekend. I got the position crank sensor off and it looked fine. Cleaned it up a bit and damn it was a pain getting that bolt back on. Cleared the codes. I noticed that maybe the wiring harness from the CTS had been cut and re wired. When I got a li...

Option A I will do after work. Option b might be a little outta my ability but I can try. Would a bad coolant temp sensor really give me this much trouble? It’s just That first start of the day that gives me the trouble then it’s running good after that. Can you give me a step by step for option b? ...

Changed plugs to Volvo plugs and changed the cap and rotor. Problem still exist. Pulling a 2 1 4 and a 2 2 4 code. I changed the coolant temp sensor a year ago and checked the wiring and it all seemed okay. Went to start car this morning and very rough start with exhaust and blackish smoke at first....

Buttttt every morning when I start it here in California it fires up but the rumble is bad and The car tends to have a bit of a high rev idle...

Going to do plugs with proper gap, cap and rotor, oil change, oil filter and fuel filter this weekend. Maybe an exhaust leak?

Would a improper gap on the spark plugs maybe have anything to do with this? Once car gets warm it will start good and drive decent.

Been having pretty weak cold starts the last 6 months. Last week I go to start my car and it tries to turn over but just cranks and if I give it gas it’s wouldn’t start to turn over but if I gave it gas it’s wouldn’t die. Spark plugs, cap and rotor, plugs, oil change, oil filter and air filter have ...

Would replacing the coil help? Spark plug gap in correct? Any help?

I have a 1993 Volvo 245 and when I start the car I have a very weak start. Sometimes I barley turn the key and it’ll start up fast but real weak. I’ve replaced the spark plugs, Ignition module and don’t suspect any hoses to be loose or not secure. I also replaced the starter about a month ago but st...
