fixing everything on a car?

[dru]

i have a 92 nissan 300zx non turbo automatic. had it 4 about 2 months now and it has now 140xxx miles on it. when i 1st got it everything worked fine. the mechanic who checked it out b4 i bought it said the transmission shifts late but its nothing big. about 1 month after having it i wanted 2 see what it could really do so at a light when it turned green i put it on overdrive and floored the gas. after it started making a ticking sound from somewhere around the engine. ive been told it could be alot of things but im not a car person so i dont know. i had both catalytic convertors changed. i am going 2 buy the best parts 4 my car b4 i bring it in 4 a major tune up (what parts do you guys suggest. sparkplugs and stuff.) now when i start the car it squeaks and then stops. would it be ok 2 just bring my car into a shop have them do a tune up and say "i dont know whats wrong with my car find out and fix it"? money is not an issue time is since this car is a keeper. i want it 2 run perfect

just be prepared to spend big bucks



like at least a few hundred just to diagnose the problems



how did i get thumbs down for telling him to spend the money on diagnosis instead of randomly buying parts?



you guys suck.

Good thing you said money isn't an issue because you'll be out a few thousand.

Why wouldn't you want to find out what's wrong before chosing a bunch of parts and having them installed.



Wouldn't you think the smart thing to do would be to see what that ticking noise is?



I'm not saying you are stupid or anything but if it looks like a duck and sounds like a duck...

Good call on your behalf.



Take it into the shop and have a talk to the mechanic, get him/her to go for a drive and give you an idea on what work is required.



HINT: Go to at least two shops to get an ACCURATE idea!!!
