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.

SOURCE: Error Code Cylinder 7 Mis-Firing & Vibration When Going Up Hill

yes i would change the plug wires , you can take a spray bottal with water and spray that wire, and if it starts to run real bad then it is shorting out, you may also have a injector going bad you can test this buy puting a ohms meter on it and ck the ohms it should read the same or close to the same as the other if not it will need replaced

It sounds like you have injector problems. You can get a free diagnostic at participating Auto Zone, Pep Boys, Kragen, etc (national auto parts stores) to isolate the problem. This may not be a fix it yourself problem.

SOURCE: jaguar s-type restricted performance

I had the same problem. Restricted performance and running rough at 3000 RPM. I have an OBDII code reader and found that the problem was in the air mass flow sensor, which is just after the air filter. I pulled this out and found it was dirty and had butterfly wings in it. The last shop where I had the oil changed replaced the filter for me but put in the wrong size. Close but no cigar. Bought some *** Flow Sensor cleaner at auto store and fixed the problem. Get an OBDII reader with the ability to erase the codes. Comes in real handy.

Hello.. looks like you are getting good fuel delivery. Is the fuel curve mixture on the scanner in specs? How is the timing, the timing chains on these engines will stretch and throw the timing off causing a ping and missfire -- a weak valve spring is something to consider. Also, the PCM may be faulty. I hope this helps.

Drove pickup and got check engine light came on while breaking. Returned home and turned on ignition switch 3 times. Got p done code. What does this mean.

Hmm. You may have reset the error code. MIL (Check Engine) codes are usually P followed by four numbers, like P1234. If the failure returns, don't play with the key. Use a code reader, or go to an auto parts store (Advance Auto, AutoZone, O'Reilly) and they will read the codes for you and tell you what they mean, for free.

How do I do a code check on my rav 4 2003

If the check engine light is on simply drive to your nearest auto parts store and they will perform a free diagnostic. The code can be read with a tool called an On Board Diagnostic Tool, OBD1, 2, or 3 for short. In my area I use Auto Zone, Pep Boys, Napa Auto Parts, and Advance Auto Parts. The connect port is located under the dash board near the steering column. The store will tell you what the code is that's causing you grief. All the best.......

My S-type will sometime read restricted performance,ABS brake, engine fault,air bag and the engine light will be on dash bored-the car will not exceed over 15mph-if vehicle is park for 15 min of longer-...

its sounds like its between the oxygen sensor..and your throttle body sensor..Normally the difference between the oxygen sensor it will display all these things except the dsc mil.Make sure that you dont wash the engine caompartment near the firewall,this can lead to water getting into the TBS and cause the sensor to go bad,and also near the MAF in the air cleaner elbow.Water can short this sensor.But intermitant restricted performance can show do to a knock sensor malfunction also it will code p0327 or the oxygen sensor.Go by Antozone let them scan the car for codes and freeze frame data.The Actron obdii scanner does well with Jaguars.

2004 GMAC Yukon - check engine light went on while driving followed by lack of vehicle power. What might the problem be?

Go to your local parts store,(Advance Auto, Napa, Autozone) and get the codes read for free and they can help somewhat of what the code means. If they can't tell you what the code means tell us what the code is and we can help from there.

My 2003 Lincoln LS V8 is losing power when i accelerate and makes a little clicking sound at the same time underneath the engine it seems like. The only thing on the dash is a check engine light. what do I...

Must read codes off of the obd-II computer using a scanner for obd-II so that you can know which system is being flagged. This is the first step.

May try to take it to autozone or advance auto parts to have them read the codes for free.

Or, you could purchase your own scanner at Sears or Walmart or your local parts store in order to read the codes yourself, and clear any that are intermittent.

If it's a hard code, as you describe, the scanner will come in handy.

Good luck on this diagnosis.

My 2003 cadillac deville-the service engine soon light came on and stayed

On a lot of cars the light is reset when you get an oil change, air filter etc. It's overdue for a "look see". You can always go to advance auto and borrow the code reader for free. Plug it in under your dash and will read and reset any codes

2003 S-Type Jaguar

First step is to drive to AutoZone or Advance Auto Parts carefully, without heavy acceleration. Tell them you have a check engine light and you need the computer scanned. They'll do it free (a dealer will charge an hour's labor even though it only takes a few minutes). Ask them to give you a printout of the codes, and post them here. Do that as a reply to my post and I can help you decipher the codes as to what they mean and what needs to be done. Was the car sitting in water deep enough to touch the bodywork, or were just the tires touching water?

2003 Audi A4 1.8T Check Engine light on

The CEL means there is a Diagnostic Fault Code stored in the Engine Control Unit. There are 1000's of DTC's, so you will need to have it read by a Code Reader. Auto Parts stores like Auto Zone, Pep Boys, perhaps even Advanced Auto often will read the code for you; but by law they cannot clear the codes. Many codes do not cause drivability problems, severe ones will trigger the ECU to run in a Limp Mode, which would require repair work before any trip longer than a few miles. Hope this is helpful.

Check engine light on and blinking

A flashing check engine light indicates a problem w/ emissions, this is why your car is not running correctly. Bring it to have trouble codes read--scanner is plugged into a port under the dash, codes stored in cars computer are read by scanner, results will indicate what is wrong w/ your van. Auto parts stores offer this service free, as well as advising u what to do. Have it checked out asap, continuing to drive it may result in more costly repairs. Let me know how u do.
