So the other day i arrived at work to notice the biggest pool of something under my car, it was my newly flushed coolant leaking right out of my radiator, i was lucky it didn't happen sooner, but my car, i wasn't holding any, so long story short, swapped out the Rad, had a new one in twenty minutes! put it in had to do it from the top since it wasn't possible to drop it where it was situated, but now after waiting a week from volvo on Transmission cooler line conencts and oil connectors to the rad, i finally have my car back, however it idles funny and the lmbda light has come on, i'll check the code as soon as i can, however, i'm not to sure whether a vacuum line has come loose where i can;t see it or was plugged in wrong, but i've traced all the line and reconnected everything and no luck, car somtime at night has trouble starting and onc ein drive it idles below 700'


Any ideas woudl help, will get the code reading asap but any reasons for bad idleing from somethign being unplugged?


thanks!

 

there is a white vacume line around the throttle body with a T in it that can sometimes get yanked when you do a rad.

 

I'm now coming up with these codes and it doesn't seem to do much with the rad but the ignition system and it happened immediately after the change.

PO172, 02 sensor bank 1 too rich, I JUST replaced this one with an OEM replacement.

P1310 Manufacturer controlled ignition misfire

P0300 Multiple cylinder misfires.

Any ideas, cap, rotor, coil, plugs, wires ?? :S

Thanks!

 

Last tune up?

 

Bought Plugs today, going to Order a full OEM kit from FCP but it the mean time i have 2 year warranty from the part store on some platinum plugs, that were on sale. I'm going to try that until I get paid and order the next one's. Volvo.

Also replacing all my vacuum's lines this week too.

Tech? or anyone i just replaced my O2 sensor with a bocsh OE and its saying bank 1 too rich, could it be finished already? like 2 months? not even, is there a reason for this? another cause, thanks!

 

If you have a vacuum leak,exhaust leak, or a misfire it can throw an O2 code.

 

okay good to know, still trying to trace the problem, put new plugs in, and a new coil, fixed one vacuum line, things running slightly better, but still not like they used too, exhaust still sputtering, will order the tune up kit very soon, but still don;t think that will solve it, vacuum lines probably still, would PCV system cause it or no? :P

Thanks for the input

 

PCV will not usually mess with the idle to much. I would check for leaks in the induction hoses and hoses like that.
