Hey all, i have been having the same problem and was wondering, after extensive searching, if any one can tell me the difference between 9091902248 & 9091902260 ignition coils, the one ending in 48 is for earlier models (03-09) and the one ending in 60 is for 09 onward. however any non genuine parts will replace both, so i am just wondering if there is actually any difference. or if any has used the later one in their 120? i have has a look around this site but found nothing, how ever i am very new to chat rooms so please be gentle

Hi tepeprado.I also used the aftermarket coils, they were a lot cheaper than the Toyota ones.They so far have been great.I still have the small hesitation, but are confident that it is not related to the coils. Currently checking and cleaning every sensor I can locate.My Prado is an early 2004 and just bought the coils online for about $150

I have a low idle speed in drive, sitting at about 500rpm......so I'm looking for answers also.
Cleaned the MAF with TB cleaner and blew out the filter. Runs great now and the idle speed is back to there it should be after a drive around the block.
I should have used a proper MAF cleaner, which is about $20 from Supercheap (for example, Liqui-Moly Air Flow Sensor Cleaner). I'm going to re-do it properly with MAF cleaner to make sure there is no residue on the MAF elements.
Maybe this is the reason for your low idle speed.
