Re: Drivabilty issue.
 

I hate to be the one to say it but get the Helms manuals.

Does the car act the same when it is cold (first started) and when it is hot (over 120 deg F H20 temp)? (o2 sensor)

Go buy a fuel pressure gauge with a drain hose on it. Connect to the schrader valve on the fuel rail on the passenger side front. (filter)

The manual references fuel or spark--which everyone else has. Could be the spark plug wires are broken down or damaged. Measure the resistance across the plug wires (boot to boot):

8/5
1/6
4/7
3/2

Re: Drivabilty issue.
 

I got the Z happy again :-D , I took it to the dealer the Rick recommended flushed the injectors 3 times, changed the fuel filter, and new plugs again. Two of the plugs fouled out from the injector cleaner. The car needs new exhaust the resonators are making noise when downshifting. Think im going for the B and B. What do you think?
The car now runs and idles perfecto! I did the nickel test and it works. I want to thank all of you for support. I also got pulled over twice on the way home from the dealer.
The cops pulled me over for no inspection sticker and after I explained the situation they were cool and commented on the car.
You are a great bunch of people.

Thanks again....

Re: Drivabilty issue.

Re: Drivabilty issue.
 

Tom,
The cleaner was applied directly to the injectors and the fuel supply was cut off. The car only ran on the injector cleaner. This process was done three times. I seems to have worked pretty well and saved me 2 grand on injectors and install. The gm part number is 58cpcr3 and a can of Bng injector cleaner in the fuel tank to clean out any carbon deposits.
Thene finally a set of new plugs part number 5614355 /41-913 plugs gapped .50. The car runs so smooth the nickel test actually works.
I will try to post a video of this.
