Hello all,

I've got a 1.6L 2001 Toyota Corolla CE Auto with about 110,000km on it. The
car is given synthetic oil every 3 months or 5000km, has had the tranny
fluid changed at 90,000km, and is regularly and well maintained. The only
major work done was my downlink cable was replaced about 7-8 months ago.

My last oil change was April 20 and everything was working great up until
that point (the only thing it ever does is periodically (maybe once a month)
it would not start right away (it always started on the second try ...like
it either didn't get enough fuel or it flooded briefly?)). Anywho, shortly
after my oil change (approx. May 4/5), I went to drive the car one morning
and as soon as I backed to the end of the driveway, it stalled. I started it
back up and it idled very low and rough ...similar to how my old carbuerated
Jeep would idle (it was a p.o.s.). I thought nothing of it at first but a
minute later I parked, got out for a minute to do something, came back to
start it and it did it again. This had me a bit worried. Anyway, for the
next few months until now, it has been doing this quite regularly - but not
every time. Once the car has been running for a few minutes it is usually
fine (only once or twice has it given me problems after being "warmed up"
but it does periodically happen at red lights).

The car seems to idle OK in park but once it's in a gear, such as reverse
when I first back out of my driveway, it idles like sh.t and sometimes
stalls. The mechanics said it might be the changing weather or humidity but
it seems unaffected whether it's cold out or warm out and has happened for
several months now. I researched on the net and some sites have said to
check the connections to the air filter (which was also replaced at the time
of my oil change) but the mechanic rechecked the hoses and connectors and
said they are fine. Last week I took it back in and they did an inspection
and told me it was my plugs which were worn right out. I had them replaced
with NGK plugs (total bill was $118 CDN for 4 plugs and labour ...is this
normal?! When I did my Jeep plugs it was $20 and took my 20 minutes ...)

Anyways, the plug change didn't do anything to help. The car goes back in on
Tuesday but if anyone has any suggestions before that that may save me time
and money, lemme know!

Thanks
