Question about 1999 Ford Ranger SuperCab

2 Answers

The check engine light is on with the code saying that there is a misfire in cylinder #5. First starting in the morning it will run rough for about 10-20 seconds and then smooths out. The exhaust has a rich smell of gas. Have changed the air bypass and the mass airflow sensor. Is it possibly a fuel injector or a crack head. 4L engine with 198,000 miles

You could have 1 of these 3 problems.

1. The injector on cylinder #5 is clogged and not injecting.
2. The Ignition coil on Cylinder #5 is not firing.
3. One of the exhaust valves on #5 is sticking due to carbon build up.

Hope one of these gets you closer to the solution.

Lets start at the beginning. Did anyone check fuel pressure before and after replacing the pump ?
Has anyone checked the fuel pressure regulator and the injector spider ? The 4.3w engine uses a spider with one injector that supplies all 6 cylinders. And it runs at 65psi or more.

check all spark plug wires and replace. age and wear and tear will cause them to crack and therefore create the misfire in your cylinder causing the engine to run rough

Check engine light is flashing while driving. It seems to be running a little rough. This just happened this morning when I started the car.


The check engine lamp will flash when the computer/emission system sees a problem that could possibly damage the catalytic converter or other components. Often the cause is a cylinder or cylinders that are misfiring which will make the engine run rough. Because the light has been flashing you should have the problem checked out and repaired to avoid any possible damage. Good luck, hope this helps!

Hi:
Usually the only thing that causes a blinking check engine light is a cylinder misfire. Usually this is caused by a failed ignition module, but to find out specifically,might take some guessing, or a computer download. You can scan the car's computer system, anf find out what codes are tripped. Most auto parts stores, like autozone,will do this for free. If you detect a cylinder misfire code, or similar, that is what you need to get fixed..

1999 Town Car began running very rough - suddenly.


When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.

Kia problem


You should get the codes checked and start from there. My Kia Sportage was also backfiring and running rough, after checking the codes. It had misfires on two cylinders. I did a tune up and had to replace one of the ignition coils. Now it runs great!
