Thanks for your help, I have changed the fuel filter as it was pretty blocked, also replaced the injectors and the distributor cap, it runs really good now except when I take off from a start still misses a bit but does not miss at idle any more. I also bought a new battery.

you more than likely have a dirty or bad injector in this situation, you can change your fuel filter and run a can of royal purple maxflow fuel system cleaner to a half a tank of gas if it is not too bad this will probably clear it up, if the low rpm miss is still there you need to bring it into a repair center and have a decarbonization done to the engine this will clean the injectors top end of the motor cataletic convertors and pretty much the intire engine
need do a tune up change spark plugs and wires.clean fuel injectors and change fuel filter.if engine equiped with distributor replace distributor cap and rotor.if vechicle still misses.could have bad ignition coil or cylinders have low compression.
engine missing could be caused by faulty spark plugs and wires,bad ignition coils,dirty fuel injectors,leaking egr valve,low cylinder compression,intake vacuum leaks.many things will cause engine to miss, first do minor fix,replace distributor cap and rotor,replace spark plugs and wires,clean fuel injectors,replace fuel filter and air filter,if this minor tune up dont help engine and engine still missing, do a vacuum test and compression test to check condition of engine.engine could be worn out have low compression by worn valves and pistons rings.
MANY THINGS WILL CAUSE MISSING AND NO POWER LIKE FAULTY TPS SENSOR. SOUND LIKE STOPPED UP FUEL FILTER, CLOGGED FUEL INJECTORS, CLEAN FUEL INJECTORS IF YOU HAVE ELECTRONIC FUEL INJECTIONS.OMIT IF YOU HAVE 2 BARREL CARBURETOR. DO A LITTLE TUNE UP.REPLACE DISTRIBUTOR CAP AND ROTOR. REPLACE SPARK PLUGS AND WIRES. A BAD IGNITION COIL WILL CAUSE ENGINE TO MISS.DO A COMPRESSION TEST CHECK FOR WORN CYLINDERS WILL CAUSE ENGINE MISS.
Here is what my Haynes Diesel Engine Repair Manual says for a noticeable lack of power, which is what you are describing.
1. Blocked air intake
2.Incorrectly adjusted timing
3.Blocked or damaged exhaust system
4.Obstruction in fuel filter
5.Blocked fuel tank vacuum vent in fuel cap
6.Insufficient fuel supply from tank to injector pump
7.Obstruction in fuel tank filter
8. Pinched or restricted fuel return line
9. Incorrect or contaminated fuel
10.External compression leaks ( glow plugs or injectors)
11. Obstruction in injector nozzles
This book has an excellent diagnosis and repair section for your engine. It's Haynes part #10330 and costs about $20. Hope this helps.
Spluttering and missing is usually one of two things Fuel or spark ?
Fuel problems will be traced to 1/ in line fuel filters .. 2/ tank run low on petrol throwing dirt and grit into tank filter ( if Fitted ) and blocked or restricted injectors a good fuel additve sometimes cures that problem , but replacement is a far better option .
Poor spark plugs breaking down under preassure oiled plugs due to overfilling or incorrect fuel mixtures .. poor or cracked distributor caps dirty or damaged rotor arms in said cap .. leaking HT leads damaged by rubbing and contact with hot engine causing sparks to fly to nearest earth disrupting the spark and ignition timing ... hope this helps Regards vortash
the blinking CEL light is an indication of a miss-fire, run the code retrival test to find out what cylinder is the one missing, at your miles it could be almost anything from a low compression issue to a bad distributor cap, a fuel injector could be the problem, run the test and get back to me, Kragen and other chain parts stores will test the system for codes for FREE!
hi there i seems that you have replace alot of components after driving for a few days to let the ecm relearn with the new components . is it still missing at low speed ? seems you may have a spark plug thats not offering up its full potential please isolate what plug is the weak one by removing one spark plug wire from plug at a time to listen to the engine and see what plug is causing miss ok good luck you could replace all but this is an extra expense take a look
If your fuel filter was considerably blocked with debris, sand of foreign material, then it is highly possible that your fuel pump would also require looking over (check/replace). In most instances, there is a strainer (a filter of sort) incorporated into the pump. Should you decide to do this, it may also help if you add "fuel injector cleaner" to your tank so as to clean the other fuel lines.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
