2006 Mitsubishi Delica 3l v6
Compression +- 200 psi on all cylinders according to Mechanic.
85 000 km
No 6 Plug were fouled. Also only one if take lead off that idle stay the same. Plugs were replaced in mean time. Can also be that No6 is dead and misfire on other cylinder ?
Def. No codes - 3 Diff W/Shops. Also if they try under Pajero no Codes or anything ?
Cannot confirm anything re Timing Belt.
Plug Dry but fouled. Colour same as other plugs.
Forgot to mention: The fist mechanic replaced valve lifters on No.6 as this was first suspect. Did not make any diff.
They tested and swapped injectors. Also the leads was swapped and replaced.
It seems they have a sort of a test bank where they connect fuel and then put elec on and check if the spray/drip etc ? I do not think they did current check or with noid ?
Yes its getting pulse according to Auto Electr.
We removed and checked cat also. Its clean and can see through.
Wil check this tomorrow with shop that worked on car.
Add. Info: If you test exhaust with paper it goes in and out like tipical valve problem. However after you rev it to 5000 rpm and engine run smooth the paper also stable.
One vacuum pipe on top of intake manif on right hand side if you look from front also pulsating not constant vacuum ? Not sure about this.?
OK will do and revert back to you. What is funny that if you rev the engine and switch it quickly off and on again it start misfire again ? That is why we thought it must be an electrical problem not a valve ? This Delica is keeping a few people busy.
No its not a GDI
Sorry for only now responding - was out of reception area.
At end it was the timing belt that jumped 2 teeth. Car is running fine now. Do not know why they did not checked it earlier. Thx for advise.
