Surging?
On my 90 civic i have an issue to settle. When i start the car it runs good. When the temp of the engine increases then it doesnt idle right. I can see the rpm surgin. Also If i hold down the accelerator the ingine doesnt idle properly. The Rpms never stay steady.
Im thinkin either a vacuum leak or improperly gapped plugs.
wut do u think?
Also the check engine light came on.but i noticed when the check engine light was on.it didnt have that^^surging problem... I Didnt think to check my led on my ecu till afterwards..but the light hasnt came bak on as yet...

Let me/us know how you made out...you're in Toronto so try Canadian Tire...my pcv valve was $3.99...
(make sure they give you the right one...if you have DPFI it is going to look like a 2.5" piece of pipe that is threaded on one end, if you have MPFI then it will look like a little "L" shaped plastic piece. They go by the engine and the year so if you have swapped in MFPI, go with the year/size [90/1.6] of the engine that the intake came from...
)
...Honda wanted $26. The hose if you have to replace that, because it is a 'molded/shaped' hose...you have to get that at Honda...but that will be (should) be under $20. Take out your pcv valve and shake it...if it doesn't "rattle" it should be replaced anyway.
Let us know...good luck.
