| | Bad gas mileage and a little hesitation!
I need help! I'm tired of asking mechanics to diagnose this problem, get charged for the fix, and then have the problem come right back! Does anyone know why my 95 Z-28 with ~70K miles would be losing 100+ miles to the tank and acting sluggish? I noticed the problem a few weeks after I ran it dry of gas about 18 months ago. I know, I know...bad! Bad! Bad! No excuses...
Here's what I've done: new fuel filter (twice), flushed/cleaned the fuel injectors ("professional" did it and I noticed improvement for a few weeks), new high performance plugs (ran very bad after awhile)...but then replaced with plain GM plugs (ran better for a while), new spark plug wires.
There's been little change in my driving habits (city vs hwy) since the mileage has taken a dive. As for the hesitation, if I punch it (no matter what gear) my stick shift nearly shakes my hand to death because of the engine vibration. It acts like I'm going too slow (giving too much gas) for the gear I'm in. But it does this in every gear. There is some improvement in acceleration once I'm over 3K RPM, but I don't want to drive my car like that from every stop light!
I know this is a lot to take in at once, but I'm out of ideas to fix the problem and I can't accept that it is just wear and tear. I want my car back the way it was before I ran it dry! Can anyone throw any suggestions my way? Thanks for any advice you can provide!!!!
