hey remember i told you guys my car was idleing bad? well i tested it today with my obd2 tester and it read that it has random multiple misfires. i kinda know what this means but how do i fix it and what caused it?

Check plugs wires and coil pack.

[Juggalo_X]

Also check your freeze frame data and see if it specifies what CYL misfired last. start with that one and take a look at the wire and plug.

[riddlee josh]

what is freeze frame data? and how do i get it?

[riddlee josh]

any help at all?

[Juggalo_X]

Most OBD2 tools support a freeze frame. unless its a cracker jack box scan tool. mine i can scan and then interface with my pc and it tells me when all the codes took place, engine temp, rpm speed all the good stuff.

[riddlee josh]

well mines cheap so i guess i can't check that. im thinking that i need to get new wires and plugs for it. but i don't know that it would help any

check your computer...mine fried to where it was telling my number 6 injector to constantly stay open so i was missfiring bad..just throwin that out there

[riddlee josh]

um ok. how do i go about checking it?

[94v6blkndred]

i took mine to a mechanic..thats all i could do..the whole time i thought i had a bad wire or injector..thats what everyone on here thought too and idk how they go about checkin the computer..

[riddlee josh]

oh well im def going to try and hope that mine is a wire but if all else fails i will def go have that checked. and did you have to get a whole new computer? and how much did it cost?

[94v6blkndred]

yea i had to get a new computer...but..i have OBD1 so it was kinda hard to find one....all and all i paid like 300 bucks for a new computer and labor..

[riddlee josh]

will it hurt the car to drive it this way?

mechanic played you
i doubt you computer was bad let alone FRIED you'd know if your computer was friend
it wouldnt run
not just say oh your #6 injector is open...thats just a bad injector
easy like $30-50 40minute job



most likely if your having RANDOM missfires in each cylinder your coil is bad
check your wires with a spark tester that you can buy at any auto store

NO mechanic will ever crack open the computer and check out whats wrong if ALLLL i mean ALL else fails they'll assume and know it has to be the computer

i bet you have 1 new or used injector depending how much of a dick the mechanic is and thats it

+1 its called a leaking injector. they are common on poorly maintained vehicles.
