Hey guys. quick background on my 05' 1.7l SOHC vtec 7th gen civic....

I blew a headgasket and had that fixed. the valve cover gasket was screwed when they fixed the head gasket and I was pouring oil over the engine for a couple weeks. Well, it's fixed now but the battery died or went bad so I replaced it. Drove it from tennessee to michigan it drove great. Next morning it turned over way too long before starting.

After that I drove it a mile and it was having trouble shifting... it would jerk like the transmission was struggling and the check engine light was on. I pulled over and shut it off. I immediately turned it back on and it ran perfectly. the check engine light was for the crankshaft position sensor. Two errors: One said a malfunction of the sensor, the other said "intermittent".

I drove it back down to tennessee just fine. EVERY time it sits for a few hours, I have to drive it for like a minute and shut it off and turn it back on before it will work perfectly.

I don't know much about these things but is it possible a fuse is blown or a battery is dead that is keeping the CPS's memory of the car? and every time it sits it goes dead and has to relearn by me driving it for a mile?


Please help me...

thanks

What do I do then? also, recently, it's been giving me further problems. It died the other day... while I was driving it. A lot of idling and slow driving (probably 15 minutes worth) and the electrical system just started dying. radio went off, then air, then the instrument panel started freaking out. Like the battery went dead or the alternator stopped working. After I started driving fast I got the power back and I haven't had that problem since. It's weird...

Also, I stalled it out again. It's been drinking gas like crazy. ANY ideas?

Indeed.
Had to make sure you got the message.
Didn't know which thread you'd settle on.

Still both, apparently.

ok now im basing this off what i went through which was basically the same thing.... get the TDC checked out and also the iac valve.. also when was the last time you cleaned your throttlebody.... the crud in the tb gets thick fast and throws the butterfly off.. making the ecu go crazy trying to recaliber the shifting points.. i learned that the hard way on an older car i had years ago.

Replacing the crankshaft position sensor is not that difficult as long as you have tools.

Most of the times when engine starts behaving the way it is for u, it is in the ignition system. If the code read crank shaft position sensor, get it replaced, that may be just ur problem. you may want to change ur spark plugs as well, that could be cause for jerking during gear change and lack of power.
