GOOD MORNING WE HAVE THIS CAR IN AT THE MIN & ITS RUNNING POOR ON IDLE ALSO FAULT CODES FOR MISFIRE ON NO3 & NO4 KEEP POPPING UP. A WEEK AGO WE FOUND THE TIMING CHAIN SLIPPERS HAD WORN AWAY & THE TIMING WAS OUT BUT ONLY 1 TOOTH! WE REPLACED ALL THE CHAINS & SLIPPERS WITH NEW. NOW IT RUNS OK AT HIGH RPM PUT VERY POOR ON IDLE. WE REPLACED ALL SPARK PLUGS & ALL COIL PACK WITH GEN PARTS ALSO REPLACED THE CRANK SHAFT SENSOR. I HAVE CHECKED ALL THE LIVE DATER & THATS ALL OKI HAVE DONE A FULL CYLINDER LEAK TEST & THATS ALL OK TO. BUT IT RUNS POOR ON IDLE WHEN WARM & THEN PUTS THE LIGHT ON. THIS CAR IS ALSO ON GAS PUT IT RUNS THE SAME ON GAS & PETROL. I HAVE CHECKED FOR AIR LEAKS WITH ARE SMOKE TESTER.
PUT STILL NO JOY HAS ANY ONE GOT ANY MORE INFO PLEASE.

Hi Craig try cleaning the throttle housing and the air mass and see if that helps.

Cheers Mick.

Morning Craig,

Please can you post emission figures and compressions so we can see what we are looking at. Also, I have heard/read somewhere that running on LPG can harm injectors.

hi mick i have romoved the thottle body & cleaned in out also reset after. but i have not as yet tryed the air mass yet as all live dater was showing ok i didnt want to spend any more money unless i was 100% because we are over £2000.00 so far

just to relate to the post from pete we ckecked the injectors but it runs the same on gas to no different misfire on no3 & no4.

hi mark the main problem was very poor running at idle & high rpm. we found the timing chain slippers had broken & bank 1 inlet cam was out 1 tooth! so we replaced all the chains & new slippers and timed it up & i no 100% that the timing is ok because i checked it again after. so now its ok on road test but idle it buts a code in for misfire no3 & no4!!

Hi, Apart from the poor running, was the misfire there?

Have you had time to get some HC readings?

Not familiar with this engine, but know LPG causes havoc with valve seats. pitting, burning and causes valve seat recession. No chance that the valve clearance has reached its minimum limit ? Looking At AD these are manual tappits, I think it would be worth considering tight tappits.

Fleet customer near us has been running V6 24valve petrol sprinters on gas and is having to fit all new seats at around 60000. They have been that much trouble he is going to diesels. Previous to that he ran the 4 cylinder petrol / LPG units clocking up 1 million Km. They still had valve seat issues with them, but they cost effective.

Try doing a compression test like already mentioned, the v 8 engines had problems with the plating on the bores deteriorating, try a vaccum guage in the manifold and see what you have,a good engine 21 inches of mercury .
If vaccum low possible causes cam timing out or piston ring seal problem as long as there are definatly no inlet manifold leaks.

hi Mark aidan lee. ok i did a full compretion test that shows no problems but i was still not happy with that so i carred out a cyinder leak test on all cyinders. that also shows no problems. this poor running at idle is the same on petrol & gas no change at all same codes come back every time. this happens more when car is at idel & warm.

Good news that compressions OK, may still be worth checking for tight tappets. small clearance alters valve timing i.e valves open early, close late and extends valve overlap. This could be an issue at low speeds

Cheers Aidan

Morning Craig,

If this thing still has problems at idle then I would have thought it would show something on a 4 gas check... which you still have not shared with us.

Hi Pete soon as i can i will run it in to are mot bay & check the readings mate its on the top of my list. just to add as will on the back 1 no3 & no4 also no1 & no2 just seam to be less affected when u pull the plugs off the coil packs but if you do the same on bank 2 no5 no6 no7 & no8 all make a big difference. seams to be poor on bank 1 over all if you no wot i mean like a cat blocked!! put i have checked that to!! I will check the hc on idel next

ok sorry its took so long to get back to you all. After co tests i found that the bank 1 was running rich. I took on wot you all said & checked the valve Clearance on all of bank 1. all the inlets where miles to tight!!. After calculateing wot we needed to remove of are shims we sent them of to be done. on refitting & a good road test the fault was rectified thank god. customer very happy thank you all for youe input on this problem fixed.
