The other day my engine light came on, on my 1999 camaro and i had it checked and it was cylinder 1 misfire. The yesterday it stared to run really bad and i had it checked again and this time it said ramdom/ multiple misfire. Does anyone have an idea what is goning on. :banghead: Do i need to change the plugs and wires or would it be a coil.

yay change your plugs...well that's what alot of people have to do however you can not count on my answer being correct

paarman97maro

how many miles? have you kept up on your maintenence?

Our engines are known for misfires... Its not uncommon, but how many miles do you have on your car?

nixon

I has roughly 76,500 miles and i've maintained it pretty good.

98CamaroZ28

I have 88,000 miles and no misfires with keeping up the maintance

wouldnt be a bad idea to do plugs and wires. Althought since this is just a random problem, Im gonna guess its the random 3800 misfire.

nixon

I recently changed my plugs and wires could it be a coil.

Misfires can be so many things its not funny. I cant in all honesty tell you something to replace.

DO NOT CHANGE YOUR PLUGS!!!!!!!!!!!!

i had a similar issue a while back that i battled for literally months. it was simple. stuck EGR valve. threw a gazillion misfire codes, lean bank 1 & 2 codes, and then sometimes an EGR code.

so after 8 plugs, fuel filter, and hours of troubleshooting....29 dollar valve.

nixon

are you positive its the egr valve and were do you get one for 29 dollars, the cheapest one i found was 150 dollars.

Im sure hes not positive, but its an option.
