Default First drive, first problem

Took the car out for a short drive tonight and everything was fine. While pulling the car into the garage tonight I noticed the idle is terrible. Not at all smooth, knocking...looks like I have to rip it apart again and see what's wrong...not that I really know what I'm doing. It seems like a bad injector...or a bunch. I replaced all 16 a few years ago with stainless and now it looks like I have to do it all over again. I'm so tired of fighting with this car.

I wish I was closer to you.....I would put a smile on your face........we would do a TOP END on your ZR-1 and fix everything once and for all. I would also do a compression check just for kicks and Ohm ALL INjectors prolly install ALL NEW Injector "O" rings. And would BLOCK TB Coolant at the Injector Housing. We would also CLEAR ALL Codes once and for all even the INFL REST if that comes on the Panel (by reseating both Sensors). We would clean up the valley and valley drain (pressure wash), redo all bolts (check all bolts on Injector Housing and Crank Case Cover) where there were oil leaks, recondition the starter Solenoid and check starter bearings and brushes, prolly a new set of plugs, and maybe a new set of Coils. Lets see......Oh ya....check ALL vacuum lines for leaks (we will have zero vacuum leaks when done including inspecting the check valve controlling Plenum Vacuum and Vacuum Pump Vacuum). We would also replace the four PCV hoses with Jerry's new hoses requiring no clamps or nylon ties (Would also get Jerrys New MAP Sensor and Fuel Regulator Hose). We would also move that rear Plug Wire Clamp (both sides of engine) up from the Injector Housing to the Plenum getting the Plug Wires up off the Cam Covers. LOTS I DO JUST TO BE DIFFERENT



I am putting a Black Label ZFdoc Transmission in my 95' today just for the fun of it. Have a Blue Label in my 91' so have a nice mix of cars and transmissions

Default Re: First drive, first problem

I wish I lived closer to either wazoo or the fbi myself. I don't have a strong owner base around and I don't have the skills or knowledge to really work on anything beyond basic maintenance myself. Last time I really dug into the car I had help from Dave Johnson.

That would require a trip to Mark Haibeck that my bank account can't cover...

I agree w/ pretty much everything Cliff said (above).

First thing I did was most of what Cliff listed - just to establish a "fresh" motor (1990). I decided that when I initially drove the car and started running into some of the issues you've had over the years.

Rather than being "nickel-dimed" to death, doing that "restart" has made all the difference. The car, except for some initial modification hickups, has run now for 20k miles since 07 and not needed anything since to keep it running well. outside of normal maintenance. (Oh, yeah... I was blessed with NOS injectors which had to be changed, but that was the "last straw", far as freshening the motor went - knock on wood...)

I doubt this latest thing is anything very big. Prolly something small (like a MAP hose coming off; something simple like that).

If you don't address it successfully by the time of the Carlisle gathering, maybe someone traveling to/from could take pity on you and "swing by"? Maybe have a "fix-it" party for a gang of ZR-1ers to drop by and have at it. Now there's a thought!?

I'm kinda in the same boat as you. I'm not a mechanic and my skills don't go beyond basic stuff. I have developed a backfire under hard acceleration from 2nd to 3rd.....It's 100% stock car. It had been worked on by the guru Mark Haibeck, before it sat for over a year on the showroom floor.
I really need to take mine on the 5 hour journey, and let Mark do his stuff. But the old bank account wont let that happen now. I think there is a picnic this coming weekend with F.B.I members, but I feel guilty showing up and saying " hey, look at my car that's not running good."

Word around the office is that I have a pretty big green space to hold a party and make a mean pulled pork and creamed corn.... Seriously though I'm so far out of my depth here it's not funny. I know what I don't know about these cars and it's legion. I get that it's a nearly 30 year old car but every year I'm spending $1,000 to get it running right again.

Last year was plugs, wires, coils, pumps, fuel filter, air filter, vac lines and other stuff I'm forgetting. Before that was the AC, before that was injectors, then there was a vac leak...If I had the money I'd send it to Haibeck and tell him to go over it nose to tail and fix everything, but alas I have rent to pay and need to eat, so that isn't happening.

Having some guys to run up to carlise with would be great too. Drive gets boring by yourself

Don't feel guilty, we're the only ones keeping these cars going. The fbi or wazoo guys would be happy to help you. **** if I knew more about these cars I'd offer to do the same for anyone. It's what we are, it's what we do. We band of brothers.

I know I shouldn't, but I do. You make a great point that we are the only ones who keep these going. The FBI guys have reached out to me, but being 5 hours away, makes it difficult......One of the main reasons I purchased the car was because of this site, and the fellow members who will do anything to help fellow members out. I just need to take them up on the offer lol.
