I Just changed all the plugs and wires on the car. The Easiest Way i found to change them were as following.

Driver side changed all from bottom.
Passenger side all from top. Hardest one is the rear one on the passenger side. The whole process took about 3 hours i did at home on jack stands. I most likely will never do it this way again. A lift could of made this a 30 min job.


On Another note i fell less power a little hesitant at low rpms. still gets up and goes i just fell less power. I used NGK plugs think im going to take them out and just go with ac delco. Has anyone else experienced this?

 

One problem I run into with these angle plug heads is that some times you think you got the plug tight but the socket can bottom out before the plug is tight and cause issues like that. When I install them now I get it snug and then re position the socket back a hair and re torque them. I check them 2 to 3 times so I know i am not bottoming out the socket. I have actually had plugs that were finger tight even though it felt tight with the wrench. The engine would idle ok but miss every now and then but would be fine under load. I would start with checking that the plugs are tight and then make sure the wires are on correct and snapped on tight to the plug and opti. I always use dielectric grease in the boots and on the plugs before I install them. This helps make sure the boot slides on smooth and allows me to make sure I here the click when the plug fully engages the fitting in the boot of the plug wire.

 

How to attack each plug solely lies on whether the car has OBDI or II exhaust and/or what exhaust is being run.
I have hooker headers and get #'s 3,5 and 7, 2 and 4 from up top and #'s 1, 6 and 8 from below and it is best to remove the starter for #'s 6 and 8. With stock OBII exhuast, IIRC I could get all passenger side plus 1 and 3 from up top and had to get 5 and 7 from the bottom.

 

Plug changes are easy when you delete everything around them and run LTs. 20-30min job!

 

with my kooks 1 7/8 headers on my ls1 on a car lift took me 18 min. it was easy i LOVE MY CAR LIFT!!!

 

yeah i think maybe one of those wires are not making good contact.Once i get out of work today im going to check them all and seafoam the car. I Just bought the car so its 100% stock. I got it from the original owner its been sitting like 2 years so theres alot of little things that keep popping up. Cant complain got it for a steal.

 

Good god I remember the days of doing a plug change with those horrible cast iron manifolds! Had to lay across the engine to get to #8! Not to rub it in but with my Jethot LT's I can actually SEE the plugs now. I highly recommend them. Save your pennies.

 

what he said. Save your money and buy good headers and exhaust. SSW headers, jethot, qtp, tsp, kooks, and american racing headers are all really good quality header that will last and perform great too. also the better plugs you buy like the iridium ones are great for close to stock cars.

 

lol i did the exact same thing laid on top of the motor to get to number 8 one.i swear if i wasnt so slim i would of never been able to get my hand in there. ill be getting some headers with in a month. just trying to do all the maintenance first before i go shell out $$$$ for the upgrades.

 

Yeah I did this job not to long ago. It sucked with stock manifolds haha

 

Pull the starter next time, and get them all from the bottom. Hop on the creeper and get your oldest boy to be your tool monkey.....Its CAKE

 

when i was stock i found dropping the y pipe was the best way, iv got fat arms, and now with headers i can knock it out on my lunch break.

 

I run the jet hots too, plugs are pretty much cake. Any tips on getting the rear driver side header bolt tight though? haha.

 

pace setter LTs and AC lines make #2 a bitch especially for people with carpal tunnel.

 

 

U did check the gap on the new plugs right? Or straight out of the box and u assumed they were at .050? Not to be an *** but u cant trust that they are correct by any means...and the crappy dollar gapper they sell at the counter is crap also, not very accurate at all, yes. How do u guys gap your plugs correctly id like to know.

 

That crappy dollar gapper I bought from a parts store.
