Update on injectors

[tomtom72]

Haber rj,

I should not stick my nose in here but I can't see you groping around in the dark by yourself! Sooo with a thought of helping out a fellow Z brother I'll offer up some stuff.

Parts: partszoneonline.com = P & G Chevy in PA, very good guys + plenty of stock. Also check out the net registry for other parts guys. LT5 Parts.com, KWhiteRacing.com...all these sites are listed over at the registry. zfdoc.com for the transmission.

As far as the fuel maps go, look over at Mark Haibeck's site, ZR-1 Specialist.com, for all the theory you need about the programing on the PROMs. You will learn alot by reading his stuff! It's like taking an introductory course on ECM theory!

The secondary vacuum system parts can be had from P & G and KWRacing, between the two you can get all new stuff to put into a restoration of the system. I dealt with P & G and KWR & got everything I needed. The trick is to have the part numbers, I bought a CD/ROM & use it to get the P/N's and then I go to P & G's site and plug them in to check avalibility. Even if the P/N's are superceeded you can call them and they will go thru it on the phone. Those guys are swell to deal with. The stuff that is NLA you have to go to KWR to get. Oh, I forgot this, KWR now has the parts book pages so you can look up the P/N's or they sell the CD.

Just a side note on injectors. If the coils fail the inj's don't fire and those cyls will be lean. The ECM will richen up the working inj's to compensate using the info from the O2 sensors. Therefore the scan tool will tell you that the car is rich and your nose might tell you the car is lean. If they leak, as in don't close then the nose or the plugs are gonna tell you that. I don't know what the scan tool would give as data in that case as only my 2* inj's were leaking. Oh, this info only comes up in "closed loop" operation.

Sorry to be so long. I hope this helps alittle. Don't sell the Z because you think parts are the problem, specially not the small stuff under the plenum. That stuff can be had factory fresh in the boxes!

Good luck,
Tom

tomtom is right...i see all the small gremlins as challenges...sometimes i hate my z too,but when i finally fix the problem,and go for a spin,i forget about
all the cursing and swearing,and i go hunting for some rustang !!

Thanks for all the information, I certainly feel a lot better now, I think what I have is what we call up here as the mid winter blues. With all these contacts and part numbers I will sit down with my guy and figure something out. The first thing will be to get the new injectors in , put the car back on the dyno make a pull and get a starting point and go from there. Like I said before I wil keep you posted on my progress.

Hey haber rj, top o the morning to ya!!!

Glad I could pay back by passing on the info! I hear ya about the "lackoZuseitis" & the "itdontrunrite" syndrome!

Look I was there & I thought now the fun was over because there were few places that could work on a Z, let alone know about parts! You're home here with us & we will not leave you out there by yourself!

If you want I can work up a P/N list based upon my little under the plenum restoration. Let me know!

Hey Blackjack, you don't talk funny...I just listen funny!

guys!!

Tom that would be very helpful to me and I really appreciate the offer. It is this kind of fellowship that makes owning these cars great, thanks again.

You got it haber! Just give me some time. I got to go to work so I'll PM you the list later today!

What yr is your Z??

[haber rj]

Blackjack I have ordered a full set of the 205 RC injectors, I should have them soon and I am going to have my stock ones checked and the good ones cleaned and resealed and replace the bad ones just to have a good set of orginals.I wanted to take the car down to Norfork in March but I think it will be a little early to take the car out of storage for that. There is suppose to be a C4/ZR1 meeting at Bowling Green this year again to honour the Grand Sport, I hope to have it ready for that and cruise down, just to drive and enjoy the ride. Who knows may be we can plan a get together down your way one weekend, and you can show me the sights, I hear that there is some ausome roads for driving, talk with you later and thanks again for the support and encouragement.

I probably wouldn't bother with this if I were you. If you want good originals, just get a set of new originals, it would be cheaper than the RC's plus new originals. And hopefully your new ones will last indefinitely and won't need to be replaced. Also, I kind of suspect that to really rebuild them to where they were like new would be about as costly as just getting new ones?

My car had injectors that really weren't too terrible, and new ones made a difference in low-speed, low-throttle driving. So if you're are bad, I suspect you will like the car a lot more once they are replaced.
