You probably have a loose plug wire on #4 cylinder.

First check for that. If that doesn't help, make sure the injector electrical lead is secure.

Next, replace the spark plug on # 4. If that still doesn't help, then a new injector might be needed. Before springing $$ on a new injector, add a bottle of Techron to the fuel and drive it. Techron will clean up a clogged injector better than anything out there.

Good Luck!

I have a 2004 3.9L Mustang with the "check engine soon" light on. I read the codes and 0300, 0301, 0305 and 0316 were up, while the car was still driving fine. Soon, it started to lose strenght, I bar


Best to read the codes first---code p0300 refers to random multiple cyl-- misfire detected causes-- spark plugs---HT leads--ignition coils--wiring.
code p0301 refers tocylinder 1-- misfire detected causes ---engine mechanical fault---wiring---ignition /fuel system ---injector---ECT/Maf sensor(Mass air flow) ECM.
code p0305 refers to cylinder 5 misfire detected causes ---same as 0301
code p0316 refers to misfire detected during start up -first 1000 rpms---causes--- engine mechanical fault---wiring----ignition/fuel system---injector. I would run a fuel system pressure pressure test as the common causes here is the fuel/injectors

My 2004 mustang gt service engine soon light started flashing for about a minute and went off also my car started


If your check engine light starts to flash that is telling you to shut it down so that you do not do any significant damage to the engine. I would recommend that you go to your local parts store or call a mobile tech out to read what codes are possibly stored in your cars computer and find out what is going on.

yes hydrailic and no will not affect engine. Engine problem is just more noticed when transmission not engaged.
Squealing is probably pilot bearing--not a big deal.
Tapping--maybe lifters pumping up
Engine light--get car scanned and report trouble codes back to us.
Autozone and Advance, among other parts stores, offer free scans.

check the throttle body butterfly for excessive dirt build up. Mine had a rolling idle and would want stall in the mornings. The dealer said it was due to my aftermarket tuner and cold air intake..............just a dirty throttle body that i cleaned.

You need to have it scanned to see what code turned on the light. Check your gas cap, make sure it is tight.

Check engine light on


There are 100+ conditions that trigger a check eng light, run a self test and get the code or codes. I have attached a list of codes, it says GM but the codes are for the most part generic to all cars and light trucks 1996 and up, any of these will set the light.

Service engine light


the burning smell that wasn't rubber is probably the smell of your brakes overheating and melting. but, if you have the money and time, go out and buy an OBD2 code reader. it should read the engine service code from the engine computer in your car. this will tell you what is wrong.(you will probably have to look up the code it gives you on the internet). or, you can take it to a regular shop and have them check the code. but if you know the code, you won't have to pay for something they say you need but don't.

good luck!
