First check for an owners manual(it will say), if there isn't one a lot times there will be a sticker on the inside of the gas lid saying what to use. However, unless to vehicle is turbo or is higher compression than stock, i am quite certain 87 octane will suffice.

The problem is with rubber seals at the entry of each plug causing oil to leak to the engine. What you need is new ones. Check the plugs affected and replace them too. By the way, oil leak to the engine will make the sub' to have a power loss of upto about 50% in an extreme case the car will refuse to start while cold!

1. No. I would not recomand the change 2. Minor horsepower increase. Not worth the money spent. Looks better than it performs. 3. Violation of federal emmisions standards 4. The O2 sensors read off the change from prior to the cat as well as after to aide in reference to fuel injector pulse(lean to rich and back). Fuel mileage decrease. 5. For true performance change, all components need to be considered(i.e. tps, cam and crank sensors, ignition components, cams, intake as well as exhaust components. Computer controlls that can be changed by the user to benefit what driving is going to be desired at that time. There really is more to be considered than just one component. Things need to work together and all need to be in sync and spec. You also need to consider the emission laws where you live and since all states have some form of inspection and/or emissions testing, removal of the cat would be detected and would fail. Not to mention illegal.

Remove positive cable to battery, Remove wires from starter. Top of motor on driver side by transmission is 2 large bolts. Very simple job. Good luck and have a great day.

MORE THAN LIKELY OIL IN GEARBOX OR TRANSMISSION,(AXLES)NEEDSREPLACING,OR TOPPED UP.WHEN OIL COLD OIL IS THICKER,WHEN HOT IT THINS AND SENSOR ACTIVATES AS IT CIRCULATES

NO IT DOES NOT...LOOKS THE SAME,BUT 2005 HAS DIFFERENT SHAPE WHERE FITTED ON INTERCOOLER.GASKET ETC DOESNT COVER THE HOLE IF YOU SAY,AND BLOW OUT OCCURS

FUEL PUMP MIGHT STILL WORK,BUT IT MIGHT NOT BUILD UP ENOUGH FUEL PRESSURE.ALSO COULD BE M A S,,,MASS AIR FLOW SENSOR,CHECK IT CLEAN IT,OR REPLACE IT..YOUR THROTTLE POSISTIONING SENSOR ALSO.IF IT MOVED OR FAULTY CAR NO GO.I HAD IT,REPLACED AWAY I WENT...OTHER SIMPLE IS FUEL FILTER

THE ONLY WAY TO ADJUST YOUR CLUTCH IS TO BLEED THE FLUID AFEW TIMES,,EG...FIND THE BLLED SCREW..GET SOMEONE TO PUMP THE CLUTCH A FEW TIMES,HOLD IT DOWN,RELEASE SCREW.FLUID SQUIRT OUT,,TIGHTEN SCREW.PUMP AGAIN, HOLD,RELEASE SCREW,SQUIRT ,TIGHTEN....THIS RELEASES ANY AIR IN PIPES,OR MASTER CYLINDER..IF IT DOESNT IMPROVE NEED NEW CLUTCH,THEY ARE SELF ADJUSTING, AND EVEN AFTER A FEW MONTHS IT WILL SHUDDER SLIGHTLY ANYWAY,DUE TO STRAIN.THATS IF IT IS FOUR WHEEL DRIVE,MORE IF TURBO...I HAVE ONE,WITHIN 2 MTHS,SLIGHT SHUDDER ARRIVES,THATS A EXEDDY CLUTH £360

remove the governor inside the transmission to get to the highest desired speed if you wish. That is done on all police cars

P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank)

no adjustment, computer controlled, you're problem rests elsewhere, do a compression test,

Rebuilding the engine is the only true cure. Be sure that the engine warms up without driving it. In other words, don't put any excessive load on the engine while it is cold. Once it warms up, the piston, rings, pins, etc. will expand from the heat. This is why you only hear slapping when the engine is cold.

if not skipping and losing power take it to a reputible exhaust shop to check for exhaust flow.. possible stopped up cat. could also be a timing problem

most proberly the bendix spining and engagging

Have you tuned it up? Does it have a new fuel filter. Any check engine lights?

Yes the gear box will interchange.

could be the auto choke sensor ,try changing it ,not sure what one it is but its on teh cylinder head somewhere

That indicates an Automatic Transmission Oil Temperature problem. Your transmission is overheating. Check the oil level in the transmission, also when was the last time you had the transmission oil changed? This could be occuring because of an excessive load on the trans(pulling a trailer) etc. Generally if it is flashing it means stop now. Could be as benign as a failed sensor, but definitely needs to be checked out.
