DomsZ28

Hi everyone. My 95 Z28 Camaro has a problem. At idle the car acts like it wants to die almost where all the interior lights and headlights flicker on and off. but as soon as i hot the accelerator its fine. On the highway the car just doesn't feel "right". I can feel the car vibrating and shaking at idle and at highway speeds. feels a bit low on power too. It does it immediately when I start it...hot or cold. Here's the kicker, in the last month I've replaced...Fuel pressure regulator, fuel filter, plugs, wires, AND the Opti(Although it was replaced with a junky re manufactured one from Autozone.....Long story...) Thanks for any input in advance.

Any check engine lights?

briefly it illuminated but after i turned it on/off it went away. I wouldnt even know where to start by checking it anyway since its a 95..It'd be a pain

You can't keep guessing at whats wrong. For the price you paid for parts that were not bad, you could own a code reader. Your previous thread explains how to retrieve the codes. I personally think using a cable with your laptop is the cheapest and by far the best option there is.

Where can I purchase a cable for my laptop? How does that work?

Search on 'OBD1 USB ALDL Cable' I got mine here ALDL OBD1 OBD cable OBDI OBD2 engine codes . Some good reading and links at this site. NOTE your car is OBD1 but since it is a '95 it uses the 16 pin (OBD2) style dash connector cable. Next you can download FreeScan from here FreeScan . Set up com port in Freescan and click Force Data interact and start communications. Or to see DTC display, there is a selection on the main screen. You can get lots of help here if you have any problems. If windows 7 or Vista I think it may need to install and run in compatibility mode, not sure, search around if needed. .

Thanks Bob, I will definately be looking into that. But the light hasn't been on for a few days now so I am back to my original problem. Any one have ideas?

You don't need the light to be on to have a stored code. Plus some codes do not even turn the light on. Have you checked to see if any parts stores have the right code reader?
