im no certified mechanic but wouldnt seem to me that would entered into misfire???????--------and why would i check any cylinder other than the one the code is suggesting????? Thanks

You roll the dice with eBay stuff. If you aren’t spending a$50 per coil, they are counterfeit.

FCP sells Bosch coil for $50.50.


thanks for the response, as noted in all that i replaced the ebay one with a new Bosch and still have the misfire--------never have i not been able to fix a ...

this saga has become even more a mystery----------after initially pulling a P00303 coDE i put a new coil ( EBAY coil i have never before had a problems with after 3 previous ones) and plug in # 3 and didnt correct the issue--STILL PULLING THE CODE . Wondering if may have gotten a bad one i ...

Pulled a P00303 code and replaced the coil and the plug in #3 and then the code became a p00304????????????----put a plug and new foil pn #4 ...

driving my 2001 s60 without PS for years now. Was leaking too much at the rack and that was a job i wasnt going to attempt and couldnt justify the cost at a shop. After burning out a couple pumps obviously i then looped the out pump hose back into the in to keep pump lubed and rack out of the whole ...

thanks for the thoughts but none of those you mentioned-----if it were anything mentioned in paragragh 2 it would reflect noticeably in how its running, just fine with no loss in power or misses as a bad plug or coil would suggest. Guess ill remove them at least and take a look though its good ...

No check engine lites to suggest some equipment failure, runs good with no misses, idles pretty smoothly. I've check the air cleaner, sprayed the MAF and ...
