Sounds like you have a leaky fuel injector. The only way to fix that is to buy a new o ring that goes on the injector. Also, check your fuel pressure regulator to see if it is leaking. Pull the vacuum hose off of it, if there is gas in the line, the regulator is bad. Hope this helps, James Booth

Why is gas coming out of the muffler


Could be a few things I can think of, leaking injector, leaking / bad fuel pressure regulator, or defective O2 sensor(s) making the computer read high air content and the ECM is dumping in more fuel to compensate. You can check your plugs for gas fouling to isolate either a single cylinder or multiple cylinders will give you an idea of what to look for. If only very fouled on a single cylinder, probably a bad or leaking injector on that cylinder. If evenly distributed among all cylinders, fuel pressure regulator. If you have a check engine light on, get the codes read at Autozone (free) and it may tell you if it is an O2 sensor problem. Random misfire or multiple misfire codes would bring me back to the fuel system components. Get this taken care of right away and change your oil when fixed, you can cause severe damage to the engine with fuel going excessively into the cylinder(s) and / or crankcase.

ENGINE MISFIRE

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

How to Increase gas mileage?
http://schematicsdiagram.blogspot.com/2011/12/how-to-increase-gas-mileage-on-2011.html---------

For car not changing gears it can be shifter assembly issue, or it can also be transmission issue. Get the shifter assembly inspected with ignition OFF.

For more troubleshooting, I suggest you to get the Following help link checked, its complete step by step procedure to inspect gear shift issues: -----

GEAR SHIFT ISSUES

http://alltypesofpartsreplacing.blogspot.com/2012/11/gear-shift-issues.html

==========




Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.



From start to end troubleshooting these problems I suggest you to check the help link below and follow its procedure: -----


Mostly all types of car no start problems are discussed here with solutions.

What causes 2005 2.5l volvo to misfire and show code random multiple misfires i replaced plugs but no good


I would take it back and demand a refund. Could be the crank or cam sensors, an intake leak, faulty coil, or a list of other components.

Vehicle missing,shaking,engine light comes on


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The shaking tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel

Po300,301,302,161,306 code numbers,what are they.upon acceleration it is like gas is having problem being sent to engine


P300 is random multiple misfire,301 is cylinder 1 misfire. 302 is cylinder 2 misfire & 306 is cylinder 6 misfire. P161 is a bad heater circuit in oxygen sensor bank 2 sensor 2. It is behind catalytic convertor. I would replace downstream oxygen sensor & clear codes. Run vehicle it may be all that is wrong.

2005 Cavalier misfiring on 2 cylinders, dumping fuel


Spark plugs get there voltage from the ignition coil packs, more then likely you have a bad coil pack or coil pack boot, pull one coil pack or spark plug wire or boot at a time, if you see a drop in rpm, that one is good, if no drop bad coil pack.

Lack of fuel when accelerating


This might help. It looks like you O2 sencor had gone bad or the signal has and causing multiple mis fire. according to your codes. 
PO171 System too Lean (Bank 1

PO174 System too Lean (Bank 2)

PO300 Random/Multiple Cylinder Misfire Detected

Causes of PO300
Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns

I'ld start with chaning the O2 sensors first but sheck for bad wire connection. Hope this helps and good luck
