Survey says p0304 Cyl four mis fire. now why would it be doing that with shiny new plugs? I cleared it and if it pops up again paul shall i let you dig deeper?

When was the last time you had a distro cap and rotor?

Hm it was before i owned it so over sixty k for sure how long do those live normally so i can look back through the records

we change them every 48k but they dont need to be changed every 48k. This is something easy too look at, 3 screws on the rotor and you can look to see what the contacts are like inside.

= bad

= poor spark

Would that explain the other symptoms as well (no guts when cold)?

Possiby, but I do believe there is more at work here then just spark plugs. As Matt said about the O2 sensors though we have seen a failed O2 sensor take out the other one too. I would like to see what your Maf is reading when hot.

Before you get some crazy ideas in your head too these are a bunch of variables that would be checked when trying to figure out what is wrong so don't go assuming that everything is broken.

Think we may have to wait until it gets cold again

Had a 98-00 R in today that ran like shit because of the ECT sensor and the thermostat was sticky, changed that and ran like a top.

=Engine Coolant Temperature Sensor...

Thanks dale! so honestly the things that might be are all nothing i can do at home eh well aside from checking the distributer cap...i may be able to scam a torch bearer tomorrow night my street lights suck so if i make it in tomorrow without throwing a code i will at least check that

You should really replace the stuff you have no idea how old it is- cap and rotor, plug wires, filters, all the maintenance stuff (EGR system, other new volvo stuff I don't know about maybe). Regular maintenance goes a long way.

Bring it in today if you can,or i'll go and pick up your car.
so it has a lambda fault now and a misfire...very interesting..

is it happening all the time now or sparadic..
and what happen you broke your fingers and can't call. Kat

Mis fires under harder acceleration me thinks...Lol and Paul I know you check here from work and by the time i pulled the code it was seven - too late to give call lol. I will leave early and bring her in this morning. Could not bring her in yesterday since i had to pick Peach up in Airdrie before six

ps. Miss Viv will now be the car formerly known as Miss Viv.

Her new name is Christine

I dont get it.
