hi, im Ben, i just bought a 2001 Volvo S40 1.9T, but i have a problem, my car doesnt haul-****!! its very slow and would like to know if anyone knows how i can give my car a little umpf! i have a check engine lite on and i scanned my computer and it gave me a code stating to check cranshaft sensor, but i dont think that can be the problem, i just think volvos are slower than most cars since they are made for comfort, so can anyone help?

Im used to driving fast, (owned a 1999 Honda civic SI turbo 320HP/331 lbs. Torque) and i know i cant get that kind of performance out of the stock motor with out replacing my stock motor with a V8. ive been reading about PPC and IMP ECU's but none are compatible with 2001 S40 AHHH!!! so please if anyone has a **** S40 1.9T please let me know what i can do. thanks!!

I have a 2000 S40 1.9T When I scanned it it said the crankshaft position was off and there was a misfire in cylinder 3. I replaced spark plugs and easy stuff then just took it to a volvo professional and it was my coils. Got it fixed and broke 140mph on the highway, I haul **** everywhere and love my volvo. I would check on your coils :thumbsup:

don't knock the volvo. there are tons of volvo owners here who have some serious rocking cars. take care of the scanned code first then see if there is any difference.

I had a similar diagnosis but found that unplugging and replugging the connectors fixed my sensor......
