so i have an 04 cavy 2.2 dohc with 5 spd, at low engine speed (2k and below) and only when engine is cold, it misses really bad and falls on its face, when it does i smell fuel really bad, any ideas?
plugs are fairly new and not fouled. what should i look for on the boots? i was wondering if the spring may be bad in them and when it warms up it would expand...they do have springs in em right? i may have misunderstood but i though they did on our cars.
I'm having the same problem. I have replaced all of my sensors and everything. I'm thinking it could be the EGR valve
check your fuel rail ( angled tube coming out of fuel rail assembly) and also check your fuel pressure regulator for leaks ( on top of fuel rail)
thing with that is though, im smelling fuel through the exhaust....i may be wrong but im leaning toward an ignition problem. only thing is i can smell a little bit of fuel on one of the injectors but cant see anywhere it has leaked...others also appear fine

did you check your plugs and wires? what bout the module on top? does yours happen all the time? mine kinda comes and goes..
The ECT sensor or its wiring is possible bad making the computer think that the engine is very cold. Once the O2 sensor starts giving feedback, the computer adjust the amount of fuel injected.
ect sensor? call me dumb but whats that?
coolant sensor i believe. I dunno if j-bodies have a seperate one for the computer and one for the gauge tho.
oic i think they do...im pretty sure my buddy had a prob with his. i just hadnt heard it called that.
