Ok my mom gave the ok for a tune up cause she heard the car start And it didnt sound to well. What do yall think it is and also what would be some good mods to get my car running well. Here are some ideas i placed below that i think may help.

Spark plugs aka fuel injectors I hear NGR or NGK or whatever is good

Opti lol hasnt been changed since well never. What would be a good opti

New airfilter K&N maybe

Elbow is also getting replaced

160 tstat.

Thats it give me your opinions please.

 

If your car has really high miles and has never had any maintenance done, then I would go ahead and do all of the following:

replace/flush all fluids (oil, trans, coolant, rear diff), plugs, wires, o2 sensors, air filter, fuel filter, maybe coil/opti if you have any issues there (check to see if you have good spark, etc)

 

I'd throw a coil at any problems I had in the spark dept before an opti. $50 vs upwards of $350. Actually do the plugs and wires BEFORE the coil even.

 

ok talk to me about the coils what are those a type of opti or what.

I thought ls1s only had those

 

And you kno my car has really high miles (sugercoating) But where do you get 02 sensors from.

 

no one knows where you can get 02 sensors from.

 

I got mine from autozone.

 

You never cease to amaze me lol Every car since, well forever I think, has used a coil. Where do you think the spark comes from, fairy dust in the Opti?

I suppose old motors could've used a reluctor style spark generator, like a small engine (lawn mower)

Fuel filter, plugs, wires. Then the coil, and then the spark control module. If still rough start, then the Opti.

If you tackle this yourself, I'd like it all filmed please

 

hahahaha ok funny man. i think i am goin to try and do it myself or get my uncle (not the one about the clutch fan) to help me. he knows his **** about lt1s. but what are the best plugs to use i hear the ngk is good, o i got the job to so you will see a lil bit of mods on my car.

 

NGK or ACDelco is what I'd use.

 

o ok im goin to try the ngk.

 

Do not get your O2 sensors from Autozone. It has been reported time and time again that people who have used the Bosch O2 sensors from any typical DAP have had problems with the car running correctly in closed loop.

The issues seems to root at the fact that the Bosch O2s do not send the readings as quickly as the factory ones do. Some people have had luck with the Bosch's, but I've heard more problems than good experiences.

Get some good 'ole AC Delco GM Replacement O2 sensors. It is the best way to go, and they'll last you quite a long time.

 

+1 ^^^^^

 

ac delco got it maybe ill get some mpg out of this tune up
