Going into limp mode? Power loss?

My jimny is cutting out when driving, feels like no power, then all of a sudden pulls again. Cut out this morning on way to site for longest time, busy a66 and no pull offs.I have a 1.6 that I desperately need to fit but think I need to find out the problem on this 1.3 before fitting as the fault will just follow? Im thinking electrical, perhaps a wire earthing? Guy in garage put snap on, diagnostic computer on it and it showed nothing? I need to get to a railway station later a prob wont make it. Maybe this engine is just about to die, any ideas on what electrical parts I could check, id be well grateful. Cheers in advance, liam

Could be crankshaft position sensor, these don't show a code, but the engine usually stops for a few minutes until it cools down.

thanks guys, coil pack and leads, where would i find these on engine i,ll try and swap em then, and crank shaft sensor will be in the engine so ok when i swap in the 1.6 then i,m thinking? cheers Liam.

No eBay APP ID and/or Cert ID defined in Kunena configurationnew ones of these then u rekon lambert? cheers Liam

Sounds exactly like the issue I had and it was coil pack/leads that fixed it.

I really struggled to find leads that were a good fit after market. So in the end but the bullet and bought genuine Suzuki leads at circa £50! Coil pack much easier to find, bought one locally and used it to identify which actual pack was faulty.

Note I ended up with slightly wrong ones from amazon despite them saying would fit, needed vin number to get exactly what was needed. But as others have said it is an easy job to do.

thanks lambert , so the above ones are correct, its looks like they fit all the engines. my 1.6vvt swift engine will have em in, i,m thinking try the 1.6 first eh any thoughts folk

yeah good thinking bat man! a damn good tip idea lambert, cheers bud , i,ll try that. spot on .

Cheers gf, ive started the 1.6 engine swap today so hope the fault doesnt follow. If it starts!! Did you find out that a coil pack was faulty?

Yes, in the end, tracked it down to a single faulty coil pack that was breaking down when hot. If you lived closer I would lend you a couple of spares that I now have so you could do the same!
