Put mid grade gas in 1998 Lincoln Continental and it started knocking on passengers side back top of motor.So i changed the oil and filter and that did nothing to help!! So was told to add octane booster and marvelous miracle treatment to the gas ... Did that and drove a few miles and it just stopped running and still had the knock.. So i replaced the spark plugs siphoned the gas out of the car and put a new gas filter and top grade gas which is all it had ever ran with before now!!..I got the car to crank but only when i kept the gas about half way down to keep it running and all the time still has the knock ... when i let the gas off some it just stopped running all together so i took out plugs and found that they had some oil on them i cleaned them and blew out each plug hole with a compressor it cranked again but still had the knock !! and would stay running as long as i kept the gas half way to the floor again ... Now i am stuck on what to do also it has a new battery but it has drained the juice from it 3 times now while trying to crank it Have had to recharge battery twice already what should i do ?
The fact that you have indicated the knock is in a very specific area of the engine indicates to me that the knock is there while idling and with you listening with the hood open. Spark knock, the kind that is caused by using lower-than-recommended octane gasoline, usually only happens when the engine is under load, not at idle.
I think you have a mechanical problem - valves, lash adjusters, maybe the cam itself. Do a compression check. If you have valves not working properly or not closing properly, this should help you find the area to check for damage.

Most likely it is a rod bearing and motor would have to be dissassembled to diagnose, you might want think about installing a low milege used replacment since it was run 5 quarts low on motor oil.
SOURCE: will not start
Check if fuel or spark problem,..all engines need both to run...use starting fluid in air intake ,..if it runs very shortly-fuel pmp?,,ck for spark at spark plug,work your way back..also ck timing belt-intact? Kev-MN

check if the fuel pump is working, if you have someone near the tank and someone else crank motor you should be able to hear a bzzzzzz rom the tank from the pump. if no noise is heard then hit or thump the tank, this can make a fuel pump start to work again, if it starts, then the pump is almost dead

For all those out there that have had problems with your Chevy Aveo Stalling, inconsistent idling, hard to start, or throttle problems, Hollywood Harv has the answer for you. Try a new Valve Idling Air Cont GM part number 93744675. You only need one and it has to be install by Chevrolet so they can place in the codes to make it work properly. Toss the old one away as most likely has so much carbon build up on the part that it stuck or struggling to function properly. It worked on mine after many different attempts at other stuff! This is a sure winner! Good luck and drive safe! Hollywood Harv
