Question about 1997 Honda Accord

2 Answers

VTEC 1.8 135K. Starts OK but feels lumpy from cold - almost like its not firing on all four. Once it warms up a bit the tickover when stationary drops to virtually zero (sometimes stalls), once fully warm runs ok but in stop start traffic tickover is erratic 500 - 1500 rpm up and down. Pulled off the distributor and it and rotor look very worn. What do you think, is this likely to be the problem?

My experience has been when the car runs badly when cold and it runs well when it warms up, it is usually an O2 sensor. The sensor has a heater on it so that the computer gets a good signal when the engine is not up to temperature.

1. My suspicion is your electronic ignition
2. If your car is a bit old, there might be a leak through your valves
3. Distributor timing gear is damaged (replace)

Just on cold start up the engine runs lumpy for about one minute, then the rest of the time it runs fine.


Make sure the block heater is working. But with high altitude and cold air this is somewhat normal for a diesel on cold start. If the glow plug indicator light flashes off and on quickly in the dash you may also have a burned out glow plug(s), this also causes a poor cold start.

Sometimes not always - puff of smoke when starting ( light colour) followed by lumpy tickover and noisey clacky sound from engine - all becomes ok when warm


I suspect smoke is just condensation in exhaust from suiting overnight. The other descriptions sound like it needs an oil change (noisy clacky) and lumpy starting sounds like dirty battery cables - clean them top and bottom. ??- When was last "healthy" tune up? Plugs, wires, all fluids & filters? I'd start there.

Problems accelerating


the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

Ford escort 1.6i 16v been running lumpy at first start then after about 30secs it starts run fine have noticed idle does drop now again never cuts out had new lambda and cat plugs leads the lot


But what is your complaint?
All cars have to run lumpy at first when they are cold, because fuel will condense on the inside of the intake manifold. You should always assume it take a while to warm up. It takes 30 seconds for everything to get fully oiled anyway. But a smaller sparkplug gap will improve cold performance, at the sacrifice of mileage.

1998 range rover p38 2.5 dse auto engine stalls


Sounds like something is overheating then and possibly a sensor. Not familiar with Rovers but might be a problem with the CAS and/or CPS which tells the ECU the motor is running and when to fire. Also maybe the IAC is bad and when you go from throttle to idle it can't control it and allows it to die.

I have 2.8L VR6. It runs OK when its cold, then


This could be all sorts of things..probably not the fuel system (it is VERY reliable, unless someone starts tinkering with it). From you broad description it could well be an ignition fault. I take it it gets lumpy as it warms up, so (in order of cost) replace the plugs (insulation breakdown), the plug leads (buy one long one and move it round the system). If you are loosing water, you may have a gasket gone.

warm up the engine and turn it off then try to turn the crankshaft pulley with a suitable wrench. if its too hard to turn by hand then the bearings might be too tight.
