Having problems with your Ford F-150 ?
My check engine light comes on and flashes on and off on my Ford f-150 1998, and it hesitates or stumbles. The engine size is 4.6 triton V8.
There is a few things that cause this. It could be spark plugs/coils and wire. You might need a tune up. It could be simple as a clogged air filter or fuel filter. You could also have an vaccum leak or leaking fuel injectors. You need to get the code scanned. Your light is on Matthews because your computer detected a problem. Autozone checks them for free. This way, it gives you an idea of where to start. Otherwise, it is a guessing game unless you check each part. That cost time and much money. See what code you get and if you still need help, you can write me or others at any time. You can do visual checks on the wire, air filter, fuel filter, and checking for a leak. This could very well be the problem. If you have the code, we know where to start.
