thanks for the reply ghosthunter. just had the car serviced for a tune up and oil change bago ko pinasok para sa paint. no problems naman. just hope the paint guys dont do something to the engine. will replace the air filter just to make sure. thanks for the advice. hopefully i can share my lpg experience soon. if weather permits, my car will be finished this week and by next week i can have my car fitted w/ a kit.
