Try having your fuel injector cleaned, you can start with running fuel injector cleaner though your gas tank and if that does not help then you have to get it cleaned out professionally or even worst have the injector's replaced if they are bad.
The other thing that will give it bad fuel would be a bad air intake temperature sensor go bad, as for the ruff idle that is common to a dirty or stuck EGR valve.
Good luck and keep me posted, by the way, what kind of Garage did you take it too? And are there and DTC codes from the ECM?

Tune up spark plugs, wires, check fuel filter, etc... Check distributor, change transmission fluid and coolant. If you need a new distributor I would try looking for a used one online.

Loss of compression in #5 cylinder on my 1990 nissan maxima


I would first be sure that you have spark to that cyllinder. Pull the wire off and stick an extra spark plug in the wire. Lay it on the engine block somewhere and atart the car to see if it's sparking. If it is, you have a valve or cam problem. If it isn't check the plug, the wire, distributer, coil pack etc.

Back then, Honda suggested timing belt replacement every 60,000 miles. If your Honda has that much mileage or more and has never had the belt replaced, now may be the time.

I HAVE A 2003 KIA SORENTO LX & IT IS USING TO MUCH GAS LATELY>>>HOW WILL I KNOW IF I NEED MY FUEL PUMP REPLACED? WHERE IS THE PCV VALVE LOCATED?


the fuel pump will not cause bad gas mileage.the spark plugs may need changing,fuel filter,air filter,plug wires(basically a tune-up),or the thermostat probably needs changing as this can cause poor gas mileage as it won`t allow the motor to get to proper operating temperature(computer monitors temp)and commands fuel injectors on longer(spray more fuel).driving habits change over time look at this also.cold whether driving also will use more fuel.pcv valve i can`t help you,maybe a parts store will show were it is if it has one.the only time you change the fuel pump is when it gets noisy or it quits altogether,or the pressure is good but the fuel volume is not to specs.

My car shakes a lot while at stop lights. Whats wrong?


Poor performance from spark plugs and wires. mine did the same thing. I tried to change the spark plugs, and found oil within and around the spark plug boots, which is problematic, but not the actual cause of your problem. If you find this, your valve cover gasket needs replacing.

If not, just get new plugs and wires. Got that done and shaking almost disappeared completely.

My car has poor acceleration and it shakes when stop also smells


Sounds like you're missing on a cylinder or two. Tune it up, first. That might very well fix your problem. Tell the part store guy you need a COMPLETE tune up kit and replace everything that he gives you parts for. Not just plugs and wires, although they would be better than nothing. I'm pretty sure this will fix you up. The symptoms you're describing are classic for a tune up.

Eng. shakes spits/sputters oil in spark plugs


I just had this fixed on my suby today. The cause is that the spark plugs, go through the valve covers on the 2.5 l .When the o rings in the cover go, the result is oil in the spark plugs. The cost of the repair in Canada was about $500 including diagnostics as well as new plugs and wires About 1.5 hours labor and new seals and gaskets. It now runs like new. This is a common problem for this subaru engine as well as for the dodge neon.

Sounds like misfire. Change spark plugs, wires, cap, rotor , fuel and air filters. Check for oil in spark plug holes. if oil found change valve cover gasket spark plug orings. they can leak oil into spark plug holes and cause misfire.
