Hi all
i am new to this forum, but I have been reading it to try and find the solution to my problem or weather it is a problem. I have just got a Mitsubishi pinin gdi elegance 2001 model on a Y plate.
the thing is , it doesn't seem to have any power. it's only done 34000 miles and was a one lady owner. i Know this because she is my mother in law. full service history from Mitsu dealers. i have been use to driving a jaguar x-type 2L which is not practically quick, but the pinin seems to be very slugish with no voom, and a 0 to 60 in, well eventually.
my question: is this normal. and if not any ideas on what my be the problem.
aslo the fuel consumption seem very high. as it is reported to be on a par with the x-type. however i am thinking this could be something related to the low power output. maybe running over rich? any ideas on both problems would be much appreciated.

thank for reading

My brother has a pinin, the 1.8 GDI. Have you tried resetting the ECU? There is a lot of electrickery in the GDI, and it has sorted various issues my bro had.

If not, you're looking at either fuel, or air issue. Make sure your filter isn't clogged with stuff, and that all hoses are as they should be. If not that, start looking at the simple things like fuel hoses, etc. The high pressure fuel pump, (expensive on the GDI) sat behind the engine near the bulkhead was an issue on my brothers.

Mitsubish had a lot of trouble with the GDI engines getting coaked up at one point, manifolds and inlet tracts full of goo from the EGR and oil mist!! not so much with hard driven cars but local town driving and short runs, they came out with a high detergent oil and a cleaning rig for the dealerships as a fix ...

Much like the Volvo S40 and V40, they suffer from being driven gently and around town, and having regular rather than super unleaded in them.

First try at a fix would be to give it a decent thrashing (a reasonable amount of time above 3.5k rpm), followed by an oil change.
Failing that, the head will probably have to come off and be de-coked.

thanks for the advise, knowing how she use to drive it does appear that the old gentle driving syndrome it the problem. we are of for the weekend soon so i will give it a good blow out up the motor way. (within the legal limit of course)

keep the ideas coming, i will post the results.

I worked for a Mitsubishi dealer in 2004 and coking up was a common problem on these engines on Pinnins and Carismas.

Mitsubishi dealers few and far between over here. Will Volvo have the same setup?

I've been giving it a good blast over the last week and there is defiantly an improvement. I've booked it in for service to in clue an oil change in a couple of weeks, I've also calculated that it is doing 25.05 mile to the gallon. how does this compare considering i have been thrashing it?

Im no expert on Mitsubishi but my Terrano was in a very similar state when i bought it. Low miles and underpowered. At first i thought thats how it was and stuck with it. When someone else drove it they commented also so i had it checked. Anyway.. long story short it was mass air flow sensor, or air flow meter. 2 screws and £56 and it was running sweetly after a long motorway run and a dose of redex diesel treatment. 4 years later still running like a gem.
