Running rough when hot - Page 4

itarumaa · Aug 13th, 2010, 18:04

update:

I have now changed the spark plugs (Volvo) and it did not make much difference.

Ok it runs a bit smoother but still at 3 cylinders,

the interesting thing is that I can drive about 24km without the problem getting active, if I start the car from cold. Since my trip to work and back is about 25km one way, this kind of suits me fine

But if I shutdown the car when it is hot and restart 10-30 minutes later, it will run at 3 all the times and sadly will stay at 3 as well.

Next Monday or Tuesday I will get the ht leads and then I know more.

ok, seems to be working, for now...

I changed the plugs, ht leads,cleaned up throttle body, idle speed valve and map (or maf ?) and ecu was reset, also the oil cap seal was changed.

Let see how it works in the future though

Ok, I found one more problem, the metal base of induction coils was completely covered with rust, so I cleaned them up back to bare metal and again more results.

Now I have to see couple of days, if I get any more problems, but it looks really good now.
