I was wondering if anyone knew the answer to problem I have.My 91 honda civic has been stuttering badly when I take off in first gear and in the beginning of the following gears.I took the head off and found a burnt exhaust valve,replaced it,along with all the valve stem seals,but it still has the stuttering problem like the timing is off or its getting too much fuel.I have all the timing corrct but still can't figure out what's wrong.Its a 91 civic with d15b 1.5 dual point injection

Umm I would try checking your distributor... autozone can test them for free... if that's not the case, check your main relay, not saying these will fix the problem but you never know... plus I'm not a genius when it comes to cars but mine recently started sputtering, but when I got a new distributor it started running fine again...

I'm having this same problem with a 91 Civic DX, after tuning up the vehicle it ran great for a week but now stutters mostly at idle. I took it to a mechanic who specializes in Honda/Acura repair and he said the compression in cylinder 3 only read 70 psi. I took it to another mechanic and he said it had a blown head gasket. No anti-freeze in the oil and it has never used a drop of oil, I'm at my wits end with this car!

Engine miss at idle is usually caused by spark plugs, vacuum leaks, incorrect timing, or uneven or low compression.

Standard compression: 184 psi
Minimum compression: 135 psi
Max. Variation Between Cylinders: 28 psi

Low compression on the first stroke, followed by gradually increasing pressure on successive strokes, indicates worn piston rings. Low compression readings on the first stroke, which doesn't build during successive strokes, indicates leaking valve, blown head gasket, or cracked head. If any of this is descriptive of your test results, there's really no way around an engine overhaul.
