92 accord runs rough few seconds (30) wont idle can keep running shortly between 1500 2500 rpm shuts down fouls plugs not the coil,igniter, plugs or wires, fuel pump runs at least @ startup too quiet to hear when motor runs to start but only catches w/part throttle kid was driving said heard noise lost power had it towed home the check engine lite cycles on/off and clicks are heard when light goes onand off the lite goes out like it is supposed to. interference engine if timing belt would it still run/turnover?

First thing, fix leaking exhaust, this can cause erratic idling...second thing, remove and clean IAC valve and MAF sensor..dry and replace, also try putting some SeaFoam in the petrol, engine oil and air intake, let sit for 10 minutes then go for 10-15 min drive...suggest you change engine oil shortly after driving about 5000kms, if the oil is old..

Did you get any codes on the misfire? If you did not, test ignition coils, test vacuum, test fuel injectors, verify correct plugs..That's right, anything from a fouled spark-plugs to burned cylinder head valves can cause a misfire. Whatever the root cause of the misfire, the bottom line is that one or more cylinders are not contributing to total engine power output. This leads to power loss, rough idle, unstable RPM and bad gas mileage...cheers

Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.

When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.

You will need to figure out if you have spark to the plugs, and if not- if you have voltage to the coil to proceed.

Possible Idle air control, simple to change on the throttle body

What kind of spark plugs did you put in it? The 4.0 litre engines in these trucks require PLATINUM spark plugs. If you put the wrong ones ( regular copper) it will miss fire and run like a bag of garbage. I had a similar problem with mine, the previous owners said "oh we changed the plugs and wires". They also changed the ignition coil not long before I took delivery. So, truck still ran like **** they said they even had to reset the inertia switch under the passenger side kick panel, everyone thought it was a fuel problem. I decided to pull one plug and volia..Wrong plugs. That also explains why they had to change the ignition coil. Hope this helps.

check fuel pump

sticking valves. the short run of the engine free's them enough to enable runnig

Try a popular fuel stabilizer like Seafoam sold just about anywhere.

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).

The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.

My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.
