Common faults on that car that cause those symptoms: Failing computer (ECM), failing ignition module, failing crank or cam sensors.
Okay, what I want you to do is visit an Autozone and have them check the fault codes (free service). A fault codes is stored in the vehicles PCM (computer)whenever the check engine light turns on.
Also MAF is extremely critical in your case, it needs probable replacement.

Yes but the spider is under the manifold... Pull your oil dipstick, if your oil smells heavy of gas, then the spider is busted. If not. check the big plug on top/center of your engine for dirt/moisture

1999 eclipse no spark


On the 2.0 and 2.4 engines there is an ignition module that fires the coil from input from the computer and sensors.
You may have to get a shop manual to have the testing procedures needed to check the module.

97 eclipse p1105, p0443, p0141, p0136


Unfortunetely none of those codes will be related! Is this car a manual trans? Seen some clutch switches go bad.. But either way double check the starter relay and even try swapping it with another one in the under hood fuse block... Depending on where you live I have found ants love to get there *** into the relay boxes for some **** reason...and they will short the heck out of em!, But the codes your pulling will not be the reason for the clicking,02 effects how it runs, fuel metering also, evap is for emissions only..

This one has the old points and condenser system?
I have had condensers cause this same condition before but your comments of bad gas or carburetor needing work or replacement are very possible.
Is it a specific "timed" miss-fire or does it seem random.
Let me know.

1999 suzuki esteem, loses power, spudders, shudders, wont go


It might be that your spark plug wires are leaking current. The current that is supposed to go to your plug is going to the engine block or other wires. Start your car and open the hood in a dark place and look for little sparks coming from the outside of your wires. Replace if you see any.

O2 sensors are going to set off your trouble light if they are giving you trouble. So will a dirty EGR valve (after fifty miles of dirtiness).

98Eclipse 2.0 nonTurbo 5speed 180,000 miles ,code PO301


The po301 is a misfire code. The backfire can be caused by a excessive amount of fuel, bad valve timing etc.
My guess is you have damage to an exhaust valve that may have occurred when you had the timing belt problem.A compression test will indicate if you have a leaking exhaust valve.The reason for the backfire is the exhaust valve is still partially open when the spark plug fires.

I got a 2001 ford f 150 off road and when i take off it spits and spudders and the gas milage has got worse wat could it be??? plugs, o2 sensors, cats


i would start with a good tune up
plugs, wires, cap,rotor. fuel filter . and clean your throttle body
a bad O2 sensor will not make it spit and sputter that is a misfire.
good luck
