Hi,My name is Tim,


I will do my best to assist you

Tim's Auto Repair :

Tim's Auto Repair :

didnt have the 3.5 in 02

Tim's Auto Repair :

are you there?

Customer:

like I said, new intake, have vacuum for top of engine, new plugs, was perfect for 2 days then ck engine light came back on and the slight miss started, then 2 days later ck engine like went off and ran great for 2 miles, then ck engine light came back on, scaned it and # XXXXX misfire and multiple misfires

Tim's Auto Repair :

ok

Tim's Auto Repair :

from the code you get

Tim's Auto Repair :

and from the way you explain the problem

Tim's Auto Repair :

it sounds as if you may have bad plug boots

Tim's Auto Repair :

this is what gos over the plugs from the coils

Customer:

crossed the coils over to make sure it wasn't 4 and it ran great so I don't think the coil packs are bad

Tim's Auto Repair :

no

Tim's Auto Repair :

not the coilpacks

Tim's Auto Repair :

the problem is the boots

Tim's Auto Repair :

you can buy the boots at auto zone

Tim's Auto Repair :

part#91920

Tim's Auto Repair :

these may cost around $50+/-

Tim's Auto Repair :

i think replacing the boots will fix your problem

Customer:

we put a new coil boot on #4

Tim's Auto Repair :

new boot and replaced the coil on 4 also?

Customer:

yes

Tim's Auto Repair :

ok

Tim's Auto Repair :

your next step is to check the compression on the #4

Tim's Auto Repair :

to make sure the cylender is sound and no blown head gasket or such

Customer:

compression is good

Tim's Auto Repair :

if the compression is good

Tim's Auto Repair :

replace the 4 injector

Tim's Auto Repair :

there is nothing else left

Customer:

well, have not done that

Tim's Auto Repair :

thats the only thing left from what you are telling me

Customer:

we did put inj cleaner in it also

Tim's Auto Repair :

injector cleaner doesnt do anything

Tim's Auto Repair :

nothing cleans better than gas

Customer:

why would it show multi misfires

Tim's Auto Repair :

i think you need to replace all boots

Tim's Auto Repair :

though you may need more on the 4

Customer:

why would it run so good for 2 days then screw up

Tim's Auto Repair :

after the tune up?

Customer:

yes

Tim's Auto Repair :

because you moved the boots around while replacing the plugs

Tim's Auto Repair :

replace all boots before you do anything

Customer:

ok

Tim's Auto Repair :

those boots are bad
