SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

They are a pain in the ****. You have to take the valve cover off, remove the fuel lines, remove the inlet valve, remove the rocker arms, then unscrew the injector out. There is no doubt, that you can do it yourself, just leave yourself 3-4 hours probably.

SOURCE: number one injector bank on 2006 dodge cummins

you'll notice on your valve cover gasket there is two connectors.. the one up front is your 1-3 the one in the rear is your 4-6... you can remove your valve cover and check the connections from the injector connectors to the
connectors on the valve cover.. check for an open.. however you could also have a fault internally in 1 of your injectors in that bank as well.. hope this info helped..

2005 diesel smart car starts then dies after a few seconds. changed pump. fuel filter, pressure sensor, cleaned air intake including turbo. Has good fuel pressure. cleaned injectors, have good spray.


black smoke = excessive fuel = bad injector tips , low injector pressure , turbo not working properly
take the car to an accredited diesel specialist professional for a pump pressure and injector pressure test, injector calibration and tip replacement

My 1992 nissan terrano blows to much black smoke .how to fix this .some say i have unbirt fuel?


if diesel and turbo , check turbo operation of for holes in the intercooler
if turbo or naturally aspirated check/ replace injector tips as black smoke indicators squirting and not atomizing
if petrol check for excessive fuel pressure, faulty injectors , leaking injector seal
regardless of petrol or diesel --black smoke indicates incorrect air / fuel ratio ( too much fuel) so injectors, intercooler, bad turbo or blocked air cleaner are all candidates for the fault

Excessive black smoke puffs out when I take off or try to pick up speed. Is it the turbo or injectors that need replacing


I'm suspecting it is a diesel you are reffering to. Excessive black smoke is due to unburned fuel. You may have an injector issue where one or more is leaking. Very doubtful as to a turbo problem causing this. I would suggest a strong diesel fuel treatment in the fuel be tried first ( possibly several applications ) to see if it helps. Injector replacement is expensive

Ssangyong rexton 2005 Injectors Delphi,,,, are there alternatives, mine at 50000km are all broken and cant be fixed according to Barbagellos The dealer is asking $8000.


talk with a diesel pump specialist about alternative aftermarket injectors but I think that you will find that $2,000.00 per injector will be reasonable for 4 cylinder On isuzu diesel the injectors are around $6,000.00 per unit.. The secret is to ensure only ultra clean, good quality diesel fuel is used. The injectors and pump cannot handle any water in the fuel.

My 95 7.3 turbo runs and idels good no miss but something is holdeing it back when u push the gas I have changed the fule filter and air


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
12.Low compression
This book has an excellent diagnosis and repair section for your engine. It's Haynes part #10330 and costs about $20. Hope this helps.

Its a chevy 1993 3500 diesel and every morning when started thick black smoke comes out the exhaust and it stalls after 10-15 seconds. after you restart no more problems unless it sits for an hour or two. ...


Sounds like a leaky injector or two.
It just takes one to bleed the fuel into a cylinder when sitting for a while.
Remove all of them and have them checked and cleaned at a good diesel injector shop.
You will save way more on fuel than it costs to have them cleaned.

Misfire on #3


Re: 2000 Volvo S40 L4 1.9 Liter L4 1.9 Liter Turbo FI

Are you consider yourself a handy person?

Swap the coil and see is the misfire going to follow to another bank of cylinder.

You has total of 3 coil in your engine.

Do a detail record map and switch the two coils.

A replacement aftermarket coil is oil $46 w/one year warranty and $55 will get you a life time warrent coil.

Do the swap and see what happen.

A leaky/failing injector can also cause the same problem.


Do a Chevron Techron fuel injector clean ran and highway ran.

Good luck

Ford-F350 7.3 turbo sluggish when you accelerate


i dont know about the turbo going bad,but i do know that ive seen 7.3 diesel have bad injectors,usually 2 at a time, check for fuel at the injector which can get messy so wear protective gear such as goggles and gloves,while running crack open the fuel line at the injector to see if there is fuel,it should run rough which is good on the working cylinders,if it doesnt change then maybe a bad injector,or not enough fuel pressure at that injector.injection pump issues are another thing,but most likely its an injector.
