ive got a rattle at around 1000rpm

[sleighty]

ok, my car is a 92 ka24de and it has a rattle at idole. and since it is also off idoling so it stops after i guess 1300rpm's but any info on what it could be. I think I have a vac leak too causing the rough idole. i have looked and have not found one but i think i can hear it but the fan distorts things.

check the timing chain w/ stethiscope and look for vaccum leaks. push brake after your car has been sitting around for a while and see if it is hard to press. that may indicate a leak although im not sure.....
