hows things lads ive an ek9 97 and when it heats up it idles all over the place for example it drops down to 3 or 400 rpm then shoots up to 1500rpm but never cuts out. then when i drive the car it drives ok. then after i hit v-tec mabey a half mile later i will have no throttle response and sometimes it comes bak after a few seconds other times i have to turn it of and back on... this does not turn on my engine light. my engine light comes on when i let the revs drop naturally roughly 1000 rpm (not using brakes or tapping accelator) when the engine light turns on it drives very sluggish and the smell of petrol its very strong... would anyone have any idea what i could be as its a very strange problem?? and also my speedo stopped working could be irelavent but i just said id say. thanks for any help :D

So is it stock condition? Well serviced? cam belt?
Sounds like idle air valve and poss a tps. Also bin the speedo converter and put back to oem to get this one prob sorted.
