Re: I have a miss fire on cylinder #1 & #6 any one can...
Since #1&6 are the furthest from the center of the manifold (if it's a 4.0) I'd suspect that either the manifold gasket is leaking a bit and leaning out both cylinders, or you have an ignition wire that has worn through a bit (in this case either #1 or #6)and they are either crossing or in close proximity to each other permitting cross fire.(not extremely likely but possible) The other item I'd check is your fuel filter. A partially plugged filter will cut down on delivery, effectively lowering available fuel when you need it most (pulling in mid range) Also, make sure your air filter is clean!

The Renault 9 GTL is a 4 door hatchback style motor vehicle with a front mounted engine driving through the front wheels.
Powering the Renault 9 GTL is an overhead valve, 1.4 litre naturally aspirated 4 cylinder motor, with 2 valves per cylinder that provides power and torque figures of 60 bhp (61 PS/45 kW) at 5250 rpm and 100 N·m (74 lb·ft/10.2 kgm) at 3000 rpm respectively.
The engine supplies its power through to the wheels via a 4 speed manual transmission.
Quoted weight at the kerb is 855 kg.
Its maximum speed claimed is 153 km/h, which is 95 mph.
#1 cylinder not firing, check spark plug, spark plug wire, remove spark plug and use a compression tester, and check the compression of that cylinder. should have at least 65 pounds of compression per cylinder. If the compression is low, you may try shooting a little oil in to that cylinder, replace spark plug, and try running motor again. if the compression is low on said cylinder, could be due to bad piston rings. requiring a motor rebuild.
Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.
I have run into an issue with these engines miss-fireing on #3 before.
You may want to have you tech check the miss-fire count for #3 & #7 on his/her scanner, THe distributor cap on these engines is made so the spark for #3 crosses over the path of #7 & they sometimes mix & become one. What happens then is they may be fooled by a spark coming through the wire if on a test lead but won't send the spark to the cylinder. The spark always goes to the easieat place so when cyl.#3 is ready to fire it is easier for the spark to go to #7 & vice-versa, So you tech will see a constant miss-fire on #3 & an intermitant missfire on #7. they can ceck the cap by pulling #3 plug wire off the distributor cap while the truck is running & there will be no spark, if he puts #3 back on & pulls #7 off there will be no spark there. the computor will only set a #3 miss-fire code because that is the cylinder that miss-fires the most.
If they find that is O/K you will want to have them do a compression test. If they find the compression is conciderably lower on cylinder #3 than the rest the camshaft theory is plausable.
The next step will cost you some money but it will tell you if you have an injector issue. You will have to pay you tech about 3.0 hrs to do this & you can just have them replace the #3 injector & hope it works. But they are around $200.00 rebulit so thats alot of money to throw at a hope. You'll need to get them to swap the #3 injector with the injector from one of the other cylinders then run the engine. if the miss-fire moves to the other cylinder you know you have an injector issue.
I hope this helps, Good luck, please let me know how you make out.
