It’s been a while since I posted about this car. It still has same issues, but have learned some things, and made some interesting observations. This gets a bit wordy, but bear with me, please. First off, I have noticed that it does use coolant, and there are no leaks that I can see. So I had a leak...

Agreed, regarding the likelyhood of the fpr installation causing the trouble. I will say, however, it started today with a vigor. Another observation, is the MPG "computer" on the dash. It shows a very high fuel mileage, like 45 mpg or more when cruising, and 34 as the average. Shows 15 or...

It seems im still battling the hard start issue. I think i have it narrowed down to a rich fuel mixture, or flooding. When i change the spark plugs, it starts perfectly for a few days. After that, it begins to start hard, misfiring and sputtering to life. Eventually, after 10 days or two weeks, it w...

The reason i ask, as you may have guessed, is so i can rule out sources of coolant in the combustion chamber. I still hope that the coolant is residual, from the previous turbo failure. If the turbo is, in fact, "coolant cooled", the there is the possibility that the new turbo was improper...

After thinking on the latest developments, i have a question. How does the intercooler on the s40 work in regard to interaction with the engine coolant. Is there any opportunity for a damaged intercooler to have coolant enter the turbo charged air, therby entering the combustuon chamber? Or, is the ...

It started good for a few days, then slowly became more difficult. Now today it started a bit rough, and i drove it a few miles. I then parked it at home for a couple hours, went out to use it again, and it wouldnt start. I pulled two of the plugs, and they look wet from coolant. Not a good sign. Se...

Did this car run before cleaning the Idle Air Control Valve?

I have been driving it since last post, and it has started fine so far. I think (hope) what was going on was due to the failed turbo two owners ago. Heres my hypothesis. Owner #1 had turbo failure, and had turbo replaced. Owner #1 sells car shortly after this to owner #2. Owner #2 drives car for 6 m...

I hope it clears up. The PO said he owned the car for about 1.5 years, and had this hard start/no start issue for a year before he decided to sell. He claimed he changed the timing belt, and coil packs in attempt to fix it, and only put 2000 or so miles on because of its issues. He said the turbo wa...

Started it this morning and drove it to work. It started easily, ran a little rough for 5-10 seconds, and cleared up after that. I drove it 30 miles into work, shut it off. No issues, no smoke. Smoke in earlier post must have been cleaner i used for IACV & throttle body. After about 1.5 hrs of c...
