Actually 3 questions. First: How often should should I get a tune-up for my 3.4 95 Camaro? Second: Do these http://cgi.ebay.com/ebaymotors/88-95...QQcmdZViewItem
actually work?
An third: When should I consider a rebuild?

 

the chips do not work, i had 1 similar to that 1 and it was a waste, i THINK you have to tune your pcm, i know i would have too but im still doing more mods... such as 3.73 posi and an aluminum driveshaft and mabye THEN ill get the tune

LOOL...... hey its only a simple resistor in a nice box to outsmart the ECM....
the ECM thinks that your engine (or intake air) is cold and enrich the air-fuel mixture....
thats all..... the resistor modified the IAT value to "cold"

the best: in Germany they say that is a new improvement from USA ....
it's not the money worth, believe me....
Some german guys have it tested on the dyno....... have a guess!
the only improvement is a little bit more fuel consumption....

 

and if you really wanted to do that, you can make it yourself with a pack of resistors from radioshack for like $0.05

Its very hard, almost near impossible to get a computer tune on a 3.4L


when you say tun up what do you mean?


If you don't know how old the plugs and wires are, just swap them, and test the coils if you feel inclined, seafoam it, replace the air, fuel filter. Replace the PCV valve and run a motor flush then do an oil change right after and put a fresh filter on.

then start thinking about engine coolant, tranny, and diff fluid.



Most that stuff lasts long periods of times but inherently most 3.4Ls have some miles and age on them. And it depends on how much of it the previous owner kept up on.

 

You can get a PCM tune 4 a 3.4, But only like 2 or three shops do them that I know of-- Texas speed is about the best.. at least thats what everyone says..

 

I could be wrong but I am pretty sure texas speed does not tune 3.4Ls. I believe they only tun 97-02 v6 f-bodies(since they use HPT)

3.4Ls are OBDI, you have to burn a chip in. There was one or two places that used to do it but I believe they have gone out of business. Its not impossible, just near impossible to find someone that does it.

 

I bought it from my step-son, who had bought from his older brother. My oldest step-son drove it hella hard; my youngest step-son drove it "ok". I Had the plugs an filters replaced THE day I bought it, also had a an engine flush, an ALL fluids changed; that was about 8,000 miles ago.

 

This ebay crap is not worth the ****. 3.4 is a VERY reliable engine, perfect daily driver, but there isn't much potential in HP gains in it from mods. About rebuilt: how many miles on engine? Is it smokes/knocks/stc? If it's running great, I wouldn't bother. If you would like a project in future, you can build it up fully forged, swap to 3.8 seriesII or LT1/LS1.

 

She's got just over 100,000 miles on her. I would love to swap it for an LS2; but that won't be for quite a while. I was looking at options to keep her running smooth till that day comes.

 

That's not a lot of miles Plugs, wires, new fluids (rearend and tranny too), new O2's (fronts), new PCV, clean MAF... CAI and catback will be nice if you don't have them already

 

Thanks for the advise; an btw, she has a catback. I know this may sound stupid, but, what does CAI stand for?

 

CAI = cold air intake

 

o,ok; already have one.
