welp since were on the fuel pump thought.
from no gas at all (i run it low a lot), and i put 20 dollars in it goes all the way up to full. then it drops very fast like 150 miles later down to nothing. i just thought the gauge was messed up.
now the backfire, when i pull into somewhere and try to show off a little i will put it into neutral and just quicklytry tapping the gas to like 2000 rpm, once( non-rice) lol. but instead of reving up there will just be a soft (PUFF) noise. and it wont rev up.
it happens like once every 2 days or so. and i drive ALOT. the car is bone stock, never touched.
and the z28 makes the 3.8 look like a 4 banger. the 3.8 is just a smother, compfy car.

z28pete.... now that you said that, the other owner did a full tune up but it still has a bad hesitation. when you floor it it takes like 2-3 seconds to downshift and take off. tps???

RE: little back fire
I too am beginning to have this problem with my 91 RS. Sometimes when I rev it up at a stop light or something. depending on how much I rev it. Depends on how loud the backfire is. I revved it up one time nearly redlining as it came back down to idle POW! Sounded like a damn drive by shooting. With the exception of only one shot of course lol . But the thing is I did a major tune up on it about a month ago. Bosch wires and plugs, coil , cap, rotor, and recently an oil change. Could it be because of the fact that my exhaust system is going to **** ? The hanger mount at the catyletic (spelling) converter is broke, so it has bottomed out a few times and now theres a hole in it from the beginning of the converter back needs to be replaced.
And, might I add that its all stock manifolds. Which when i have the time and money .... i plan to put headers on it and run true duals back w/ cherry bombs or flowmasters.
