2000 Honda Accord LX 4 cylinder 2.3 liter engine, rpm surges, won't stop reving up at start up

Sound like you jumped a tooth on the timing belt. Change it immediately. If it jumps more or completely fails you will bend all the valves. Just make sure you time it correctly. However a bad Mass Airflow sensor would cause the RPMs to go crazy. But the pinging is most likely the valve tapping the piston and needs immediate attention as well.

1995 ford ranger failed nox at 15mph All other readings passed.

If the Exhaust Converter is original to the truck,replace it

They only last 12 to 15 years under perfect engine running

Also the EGR Valve has to work correctly & you can not
have any overheating issues,from anything,cylinder misfires,
coolant temp,old O2 Sensors, with 100,000 miles on them

SMOG test passed ALL except "NOx" results were 696 Limit is 585. Any easy fixes ??

I've had good luck using CRC's "Guaranteed to pass" fuel system cleaner. Follow the directions exactly. It should bring all the smog numbers down--perhaps get your NOx number low enough.

If the EGR valve is not working properly, it will lead to high NOx. Check for a leaky vacuum diaphragm on this valve. It will not only keep the EGR from working when it should, but also lead to a lean mixture that burns hotter, thus generating even more NOx.

Check for vacuum leaks. Any extra air that makes the mixture lean will contribute to high combustion temperatures and high NOx--even if the EGR valve is working.

Finally, if those steps don't work, it could be your catalytic converter is getting old and inefficient. Don't be surprised if you need a new 'cat.

Engine is suging real bad. at all speeds.

Mine did the same thing. I thought the fuel filter was clogged, but when I put on a new one, it did not solve the problem. I took it to my mechanic and he instantly knew what it was. He replaced the EGR valve. Fixed it. Also, a bad EGR valve can ruin a catalytic converter so you might want to check that also. I ended up replacing my catalytic converter right after the EGR valve was fixed. Got a catalytic converter that let the exhaust flow free-er. Getting 24 mpg on the highway now.

Cannot get my 95 blazer lt 4door 4.3 litre v6 to pass emmisions at idle.tried new hotter plugs,new cap an rotor.wires.fuel filter.can anyone help me with this.everythings fine except the idle is high on...

Hotter plugs, are for when your getting too much oil on them. Fuel filter has no effect on emissions. Did you put a light on timing? Air filter clean? EGR working? Check 02 Sensor? Getting any codes stored? Converter not rattling,when you bang on it with your hand? Oil clean,try full synthetic. PCV system tight,no leaks.Don't throw parts at it. Always test,to be sure you even need to change parts.I'am not a fan of injector cleaner, but in your case!!

Fuel Evaporative Control Functional "failed"

that is a heat problem there are only two components on the car that effect the NOX and that is the egr system and the catalytic converter. to check the egr valve start the car up let it idle diconnect the egr valve put a hose on it and **** on the hose if the egr is good it will get a erradic idle you will also have to check the egr soloniod to see if it is working you can do this by removing the hose from the egr and reving the engine if it starts to **** when you rev the engine then it is working if all of that is good replace the catalitic converter and it should sail through.
