Sorry to ask, but Iv looked over the last few days at how to test my O2 sensors, and can't find what wire colours to test, and what the reading should be (hot, cold??) I'm sure someone will know on here. Many thanks in advance

How you doing Emtee, not been here for ages (work boo). Yeah the software bit seems way out, but a MAF is a quick change and not too pricey, and does control the whole runnings of the show when cold and warm. Sure I can find a bosch one somewhere rather than from maserati.

I did read on the good old web only a few days ago, about a guy who had owned his 4200 for 3 years and had the same poor pullaway when cold, and boggy throttle low revs as I have. Turned out, his ECU was loaded with USA map ?? once cleared and sorted, ran fine, but surely the maserati's in...

Sorry, Iv not been on a computer for months as been away, and yes. MIJ are ok, they seem to know their stuff and weld very well. I had a pair of 4200 rear boxes fitted recently by them and they are made well, and fitted well. They seem to work on a volume basis to earn their upkeep, whereas most...

Hi All, Really weird, iv been enjoying the car whenever I get the chance since sorting my last problem of the standard cats blowing up, then replaced them with gutting the primaries, and welding in 2 stainless 200 cell secondaries in place of the big boys. Been driving occasionally for 3...

Ha ha, i'd say 8 miles is fine pal, I personally went to the next street and back (lazy 6it I know) but I did it and the next time I started it, it was fine, then revved it up and the engine just bogged down and got engine lights, and within 4 mins, got the slow down message. Was narf scarry ...

I've just gutted my two front cats (because they both crumbled into the secondaries, previous thread) and removed the big rears, and welded in 2 stainless bodied metal core 200 cell cats, and it sounds excactly the same as the car on that clip. I've also got an X pipe and through rears BTW, and...

Thank god you told me this. No joke, i've owned my 4200 for ......guessing over 6 months now, and only yesterday since doing the cats did it start making this excact noise. I thought it was the fans kicking in for some reason, and was going to call Mathew tommorow about it (he's looked after...

Also I found out the main reason the ceramic cats break up (apart from damage and fatigue). If you use the car for short journeys during winter time, the front ones especially become full of condensation from the short run, then hold the water for ages as they are just porous soft plaster, then...

Well, bit of a shock to empty the pipes and have this lot fall out of them. But it did confirm the problem. Never thought it would happen to me, just read about it happening to others ..? Well, i've gutted both fronts now and cut off the rears before they go boom, and TIG welded a pair of...

Absolutely what I meant, spot on. I needed a pair of O2 sensors for the car, and Mase-rapey wanted a huge amount for them, literally astonishing, then I purchased the original Bosch parts from World Car Parts for £70 each (a quarter of maserati price !!) , and it seems that every other...

Ok, i'm not going the larini route under any circumstances, at 2500 pounds for a pair of pipes ????? its a 4200, not a veyron. Been tig welding for 25 years, and have a nice pair of new 200 cell stainless cats here ready to weld as replacements for the rears, and going to gut the fronts (which...

Hi all, Been enjoying the car until the other day, when I was on my way home and suddenly the engine revved bad, and exhaust sounded like ****. Then got the engine light on with SLOW DOWN flashing, then limp mode.................. Upon finally getting the car home very slowly, I let it...

I get that too, mine are always spinning ???

Mine sometimes goes forward when tilted, sometimes (more often than not) don't, and iv done the seat reset and battery reset a few times, and sure it behaves for a period, then goes all Italian again :confused: I'm absolutely positive that if everything works perfectly on these cars, you must...
