Finally signed up here. Ok so 2001 civic ex sedan manual trans 167k. While driving sometimes I'll notice the car not accelerating while in gear then I drop it in neutral and the rpm gauge slowly drops till it hits the bottom and the car stalls. I can usually re crank it no probs immediately after. Sometimes when I recrank the engine seems to run very very rough and will not rev past say 3k rpm. If it wont crank up I'll let it sit and it will 5-10 mins later sometimes I've taken the negative cable off for 10 mins and it resets but then again I've had it stall multiple times after starting to drive again. The only conditions I can link are it is hot outside and I've been driving 20+mins or sitting in traffic 5-10 mins. Sometimes I can drive 45 mins while its hot and it's fine. I've done alot of work to this car and it's frustrating to still have an issue. Only check engine code is p0420 for the cat (replacing next month). I have a list of things I've done to the car along with at what miles it was at when serviced. Ask any questions you need will provide answer and mileage. Thanks in advance for your help. BCL

clogged cat is potentially a factor.
try farting while someone plugs your exhaust...

Yeah I've heard a clogging cat can cause a few different issues. From blowing the head gasket at 153k and all the oil it used to leak I'd say it had enough antifreeze and oil get in the to ruin it. Farting what now? Lol thanks BCL

Could back pressure from a clogged cat cause the spark plugs to lossen up over the course of a few weeks. That's the only thing I can think off. I've of course replaced them and torqued them while the engine was cool. But once when it stalled i noticed they had come loose about 3/4 of a turn each less on some most was the 3/4 one. Thanks BCL
