There can be a couple of reasons for your idle being eratic. one of which might be the carb. try cleaning it with carb and choke cleaner. if that doesnt do anything check all of your fuel lines lots of times there might be a small plug which would be slowing the fuel and not letting as much get to the carb. also check your fuel mixture screw.
You don't, fix the vacuum leak that's causing the eratic idle conditions

when engine is first started cold it will have a eratic idle till it warms up some this is my experiance
If its the fuel injection model sounds like idle air control valve need cleaned out.
This is a very common fault on these cars (i've had 5). Two of the most common causes of which are 1. A dirty idle control valve - Find, remove, clean and reinsert it. 2. broken Lambda sensor - replace original
The idle air control valve is located in the throttle body assembly itself. It is a straightforward replacement part that runs roughly $200 at the dealer. This part may cause driveability issues including idle surge, check engine light, poor deceleration and eratic shifting.
it sounds like your low on freon. the idle kicks up to comensate for the extra load from the compressor . if its low on freon the compressor short cycles causing the eratic idle
Reckless
Check Rubber Inlet Hose from air filter for cracks (need to wip it off to properly check-----as for slow pulling away,if the brakes arn't binding check spark plugs..
battery cables not making good contact with battery
No. Try erratic. Do not try erratic because it doesnt show up to anything else except for this same question...and you can only use eratic in a baby sentence so you basiclly wont know what it means...sorry...hope that helped a lil bit
get the bulb replaced in the light of the side that's blinks too fast
