hi guys i'm new to all this but i'm looking for some help please :( i have a eldis autoquest on a 94 plate . the problem i am having is i get a judder as if it's missing after every gear change. it lasts for about 5 seconds then seems fine. i think it's mainly second gear. i also seem to be losing power when going up hill's. my best mate timed the ignition timing but it's still doing it. it's a 2lt petrol. can someone give me some idea's please and no i dont want to scrap it lol. thanks for looking. have done all checks and she still missing after every gear change. carb has been striped down and cleaned was hoping that was the problem but she doing the same. new fuel filter on her. all pipes fine and working. well my day's of a motorhome are gone. sick of losing sleep over it now. thanks to every1 for tips and cheers aliz1967 for all time and effort you have put in........................................... takecare guys n girls and happy motoring.

Haven't worked on one of these engine's for some time, but it is worth looking at the vac pipes coming from the distributor to the twin cards, as they double up around the carb and have a habbit of splitting or simply falling off!! The needles in the secondary part of the carb and it's needles also can get comtaminated on this particular model, hence why there can be a slight delay. Normally bit of a pro's job, but if it has never been done or not done for a while, it's worth having the carb stripped and all needles/jets cleaned up.
Good luck ;)
 
Could also be a spark plug breaking down under exceleration.
 
Check LT connections

I had a similar problem with my 92 Autoquest it started backfireing sounded like 'popping' then occasionally cutting out:mad: but restarted:). Checked all ignition wires HT/LT found one of the LT connections (Spade crimp) on ignition coil (front of engine size of a coke can with main HT lead coming out to distributor) loose, nipped this up with pliers, no problems since.
Hope this helps ?
 
thankyou for that i have looked at the area you say and they do seem to be in bad condition. a job for the weekend i think. thankyou again for taking time out to help me with problem




bob:)

Elddis 2ltr problem/fixer

Yes mate i have the same vehicle and had the same problem ....but in Bulgaria ! at least your in the UK.
If this works please let us know....
Theres a small clear petrol filter in the engine bay,take off and replace,job done ???i know sounds stupid but thats what was giving me the probs..
( in frustration,i was putting my foot to the floor on the exelerator pedal,which blew my exhaust apart at the time !!!sounded great (like a tank)cruising the hotels and beaches of Bulgaria,till i drove home,inland)

missfire

would try spark plugs as mine had slight missfire after you change gear as you tend to put your foot hard down then ease back plug was breaking down under load
 
Quick update.

Reset valve clearances(tappets), engine a lot quieter, Increase on power. above all most of the missfire/judder is eliminated.

Its Looking good !
 
See if you can get hold of a timing light (strobe light) and check the ignition timing. You can also check that the automatic advance/retard is operating as those two things could be part of your problem.

You should check them anyway because if they are out then you have less power and burn more petrol.
 
HI. Have already done this.

What a pig of a job , had to remove the alternator to get to dee the timing marks on the front cover. , and checked the advance was working.

Alan.
 
UPDATE
Today we repaired part of the loom distributer to Ignition pack the (plug/socket was corroded) this didnt make any difference.

We adjusted the 2 mixture screws.This helped but didnt cure.

Last we stripped the carb. AH. It was full of rusty crap.

Nickjvanbitz was originaly close saying jets.

Anyway cleaned it out , using compressor blew jets both backwards and in reverse (If you know what I mean) to clean any crud out , blew all the airways clear etc etc.

Put it back together , Hey presto drives 99% as it should.

But It leads us to beleive the Fuel tank is full of rust, and the fuel is all contaminated. So Tank needs to come off and drain ,Flush and refil (or get a new 1).

But for now the Fuleing needs seting up on a CO meter. Then Job done.:D:D:D

So a BIG THANKYOU to everyone who has contributed.

There should be a filter in the tank. While you have it off, fit a new one and a new inline filter as well.
 
elddis update

we have done all sorts to her and presto she is doing the same misfire after each gear change. she was fine until i left her for a day then when i started her up she was doing all the above again.:(. dont know what to do now. have checked all pipes they seem fine . looks like my days of camping in motorhome is coming to the end. as i have had enough of losing sleep over it and not being able to use her . been under bonnet more then i have used her.
anyway thanks for all the ideas and cheers aliz1967 for all help on her........................ :(
 
The only thoughts I have left are the following;

Fuel Pump - may be a very tiny leak back in the unit allowing the drop in pressure when you have throttled off.

Fuel Pipe - this is aimed more at the pipe going to the pump, rather than from it!! It may be drawing in air and if it's the fabric braided type, you may not necs see the leak at first.

Worn Needles/Jets - Don't rule this out, especially if you found alot of muck and rust in the carb itself.

Ignition advance in the distributor - check to make sure it moves.

Regards

Hi Nick.

We had checked the fuel pump ,loads of pressure and high delivery rate.

Worn parts in carb is a distinct possibility , Especially needle valve.

Misfire reduces as mixture is alterd- This still needs to be set up on a machine !!!!

The Ignition advance does work but we have no way of telling how much advance we get I estimate it at about 30 degrees under full load., Static timing is set at 14 degrees btdc (I NEED TO CHECK EXACT FIGURE)as stated in the workshop book allowing for unleaded fuel.

The carb has been fully stripped , clened and blown clean with compressor.

Any more Ideas Please please.
 
14 degrees BTDC seems excessive. It is usually just a few degrees.

Get the engine fully warmed up and then loosen the clamp on the distributor just enough for you to turn it. Start up and move the distributor body in very small increments. There should be a point where it ticks over better. If it starts racing a bit then adjust the tickover control on the carb to bring it back down again. Give it a blip of power on the throttle linkage to make sure the revs pick up smoothly.

If you can get an exhaust gas analyser to stick up the exhaust then you can eliminate faulty timing and mixture. Then it has to be a physical fault ie; mechanical or electrical.
 
I totaly agree about the Timing. We adjusted that a couple of days ago the autodata disk we used is wrong.it said 14 degrees BTDC :mad::mad:

Just checked the russels manual for the late 1994 engine on unleaded should be at 6 degrees btdc. :eek::eek:

We know its 8 degrees too advanbced , that explains quite a lot :):).

Will reset that tommorow. then off and get mixture set up ..:rolleyes:

THANKYOU "Maingate" once again
