Question about Cars & Trucks

1 Answer

Check engine light was on in 99 Mercury Grand Marquis, went to autozone to run codes they came up as F1131 and F1151 which was for fuel injectors. I was told that Lucas Oil Fuel Injector cleaner would solve problem, is this true or is there a bigger issue?

    Also car sometimes chugs a bit in the morning when I start it, I let it warm up and the chugging usually goes away after a couple minutes. And it is not a very noticeable chugging.

Gasoline itself a solvent, therefore its an excellent injector cleaner in of itself. No additives I have ever used worked, ended up replacing things anyway. Save some money, don't buy the lucas treatment, get some new injectors installed. Might not be a bad idea to change out your fuel filter also.

Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.

I recommend getting a repair manual from an auto store for your vehicle. They run $15 to $20. It will tell you exactly how to do everything you asked and also give you the values that should be expected. Hope this helps.

SOURCE: check engine light on

I had to do some digging to find this info: The code is P2716, which is a problem with the 'transmission pressure control solenoid D or it's circuit.' It is located on the transaxle valve body. There apparently is a technical service bulletin (TSB) # 1406 concerning this. If your Corolla is still under warranty, the dealer will fix it, which is, according to what I could find, replacement of the computer that controls the transmission. The bucking problem you described may have actually been a transmission shifting problem, a symptom of this code the cars computer threw. If you did get some debris drawn out of your gas tank due to the low level, the injector cleaner might help, but it has nothing to do with this code. I would recommend you have the fuel filter replaced (to address the low fuel tank, possible debris drawn into fuel line issue), and check w/ the dealer about the TSB, it covers '05 thru '07 Corollas.

SOURCE: engine runs rough at idle and bucks at highway

I had a similar problem in a 1994 Taurus, and after spending nearly 300$ on ignition parts, it turns out the problem was a bad spark plug wire that cost me 8.88$ to replace.

Car stop running just cut off.could it be the starter.

No the starter has nothing to do with your car staying running you should check fuel issues fuel pump injectors regulators. Also most likely check ignition components spark plugs spark plug wires distributor cap and rotor or coil if equipped either or and check coil pick up sits underneth coil packs i would go to advanced auto parts and they can check coil pick up and coils or you can by pulling out spark plug and putting it back in wire set spark plug next to engine block if you see blue spark coil is good if orange bad not hot enough to ignite gasoline. is your check engine light on if so get codes read for free at autozone or advanced auto could also be crankshaft postion sensor or camshaft postion sensor lmk if it helps. if it helps please leave 4 star reviw and good comment thanks

Cutting off at the light

Thanks for choosing FixYa and welcome. There are many things that can cause this. A clogged air filter or fuel filter can cause this. A leaking or bad fuel injector may cause this also. You may have a vacuum leak causing the stalling. Check all of your lines. It may be a sensor that is the issue. If you have a check engine light on, get it scanned at Autozone or Advanced. It may show the cause of this problem. That is your best bet if the check engine light is on.

1999 gran marq has new alternater,fuel pump and filter,spark plugs and boots but still skips while idleing and mostly while accelerating,,,getting worse also

I will try to add a few things to check. It sounds like bad plug wires or a coil going out. Sometimes if you water mist the coil and wires with a spray bottle you can see the sparks jump. It will be easier to see in a dark area with the motor running.

The Intake manifolds were changed from metal to plastic to prevent carbon buildup in the EGR passage. This would be under the Metal Airhorn and under the gasket where it attaches to the top of the Intake. There is a groove to clean that carbons up and throws bad codes and interferes with the engine running good. 8 bolts and a $10 gasket and 1Hour of your time to fix it.

You have not mentioned any codes or testing results. Your onboard computer can be checked for free at Autozone or Oreillys. Your "check engine" light should start setting defect codes if your misfires are getting worse. Also, if you can remember a wet plug when you removed your old plugs, that would be a good indicator of a bad wire for that cylinder.

Let me know if you have been fixed.

My car cuts off at low speed, usually when stopping at traffic lights or after crossing grids in road. Will restart in a few minutes. It cut off 5 times in one day but always restarted.

The EGR valve may be sticking open.... most likely ...

Possibly clogged fuel injectors... (not as likely). Use a brand name fuel injector cleaner ($6 AutoZone) or "complete fuel system cleaner ($8 AutoZone). No store brand stuuf, just name brand.
