Hi, my name is ***** ***** i will assist you
Hello. My name is ***** ***** I will be assisting you today. Was the replacement coil new?
I will advise you to replace all plugs, and the remaining coils. When one coil goes that is a sign that the rest are on their way. That's why techs suggest changing all. Short of that, you should make sure that the coil didn't leave any debris in the cylinder that would prevent connection and spark. Make sure all the plugs have the proper gap. Also, make sure the connectors are receiving the proper voltage.
Verifying the timing is something that I do just to eliminate that cause..
Have you check to see if you have an intake hose leak?
Or a vacuum leak?
Do you hear any hissing or sucking?
You will need a pressure tester and a vacuum tester. These require the specific pumps.(vacuum pump or compressor)
These two issue will cause each of those codes to set. Check around the brake booster hose most commonly disturbed. Especially with recent work done.
Yes. I think your vehicle is having a breathing issue. That is a great possibility. I would have your local shop perform pressure and vacuum test.
Safe for you, yes, but not the vehicle. With the vehicle running rough, it may cause other issues. I wouldn't advise it.
If you're going straight to a local shop, it may be okay.
Your issue is definitely frustrating. I still advise getting the pressures checked.
That is a sign. Lets hope its coming from the top.(plug stem seals). Have you been emitting smoke from that tail pipe?
Ok. Just checking. The the next step is the pressure and vacuum test.
No problem. I hope it all works out for you. If you have found this information helpful, a positive rating would be greatly appreciated... Thank you..
As long as you have a vacuum pump also, You should be able to perform the task.
Harbor freight. And the test is difficult to explain. It would be best to check for a video of the procedure so that you will have a better understanding.
Yes. It will make it very audible..
I sometimes spray soapy water to help locate the leak easier.
Not for the vacuum test.
Not if you have a pump.
it shouldn't, but I would attach it to the main hose running for the booster to the intake..
Disconnect the hose from the brake booster and use that. The brake booster is located behind the master cylinder(the place where you put in brake fluid.
