first of its very weird because i know the car has been serviced reguarly by toyota, i recently bought the car and yeh shes mechanically A1 besides the lights which only come on every now and again..

i was browsing around and came across this.. http://www.mkiv.com/techarticles/eng...bd1_codes.html

"The ECM stores the code(s) until it is cleared by removing the EFI No. 1 fuse with the ignition switch off."

First off i know that oil is fresh as i change it every 3000kms with motul chono v, and replace the oil filter and use e30 engine treatment. and i know the oil is at the right level.

next is if that cat symbol with the heatwaves means coolant/overheating thats impossible because the cars temp gauge does not show any overheating, however though when i do turn the car of i hear gargling sounds.. coming from the coolant pipes. if anyone has something to add on that please do.

with the rear light symbol, i guess thats my rear lights which work well except for the small centre brake light with the leds, i have about 4 which arnt working but im pretty sure that shouldnt show up as a fault?

and battery, car starts up fine everytime, alternator is good.. though i do have a sub connected (previous owners) maybe some faulty wiring.

Ok, this is what im planning to do..

oil change & new oil filter plus e30 engine treatment and oil flush
coolant flush, then coolant chnage and bleed out any bubbles
spark plugs iridium ngk's im thinking BKR6EIX-11
flush brake fluid via bleeding, then new dot 4 fluid
transmission oil change castrol vmx, with nulon g70 treatment additive
and last but not least air filter clean

after all this i plan to disconnect the battery, then reconnect it start her take her for a spin.. and if i still get the warning lights ill refer to "The ECM stores the code(s) until it is cleared by removing the EFI No. 1 fuse with the ignition switch off." and give that a go.. if the lights still come on im screwed guys

PLEASE DO add any suggestions or comments!

Gurgling means air in the coolant system. It'll either bleed itself out (if you fill your overflow tank), or you've got a leak somewhere.

The taillights will show a fault if a bulb is burned out, or if the bulb used is the incorrect resistance.

Don't clear the code(s) - these are the keys to fixing the underlying problem(s). Tell us what the code number(s) is/are that you get, and we'll help figure out the problem. Most likely it's not related to the fluids or plugs...
