Hey, i have a 93 V6 Tr automatic. Sometimes when i accelerate it makes a sort of chugging noise and you can also feel the car struggling to accelerate. It feels as though something might be blocked but not sure. Let me know what ya think

Sounds like its missfiring, best to check the basics, plugs, leads, clean injectors

I had the same problem in mine, you could try a higher octane fuel (95-98 RON, 91 unleaded doesn't always achieve the best results in an old engine), renew your fuel filter, change your plugs for a hotter/longer type, to alter your timing slightly, if your leads look terrible, change them, check your distributor for fouling, check your air filter, run a bottle of injector clean through the engine, check your transmission oil level and colour, check your engine oil, the list goes on...

By chugging I assume you mean it just trundles along like a truck, picking up speed slowly? Does it happen all time time or only when it's cold?

do u have to take off the intake plenum, to change the rear bank spark plugs, on a V6 2nd Gen ?

If you're feeling adventurous and don't have an aversion to twisted limbs, then no. The 2nd Gens were the first to come with platinum plugs on the rear bank, to avoid this very problem. It CAN be done without removing the intake plenum, but you need to pull the air intake pipe off to access the LH cylinders, and reaching in behind the distributor while squeezed in under the bonnet isn't exactly easy...

fair enough i just couldnt remember, we used to have a 2nd gen but i never changed the sparkies, we had someone else service it so i wasnt sure. in reality u will have a similiar problem with all V6 east west front wheel drive cars wouldnt u.

You sure will, from memory it's even harder to change 3rd gen rears, cause the 3.5 is even more packed in than the 3.0...

When Mitsubishi put a north/south engine in a sedan they'll sell like other sedans... although I guess we'll see how the 380 pulls up in a service environment pretty soon...

Same thing happened on my old TR... turned out to be the leads and plugs, they were dirty as hell and the car was only running on 2 cylinders.
