I have searched and found numerous answers to the question, but need a little help in saving money so I have taken it a step further. First off, I am driving a 1993 that has been sitting for 3 years. Love the car, but after the first full tank of real gas I developed a problem. (not sure if it is related to the gas) After first I was doing some spirited driving seeing about the up shift indicator and what not and had no problem (just a little missing here and there). After words, I tried again and couldn't get it above 7 PSI with out it cutting out/shuddering which felt like a Rev limiter. I was scared for a second. Limped back home for some underhood investigation. Everything looked fine and double check the filter and MAS. Tried it again and the same thing happened. Since this was my primary transportation, I didn't want to push it. in traffic the car acts normal, but as the car heats up, it starts doing it earlier in boost. With the car hot, I can't get it above 2 PSI without it bucking. Plugs have little miles on them and I just replaced the wires on a hunch from this board...Same thing. since it is related to heat, is there any quick diagnosis? I also ran a pressure check on the fuel rail and it stayed the same (32 PSI) up until the throttle was let off then it dropped to 24 PSI but went right back to 32. Also changed the fuel filter. Have it narrowed down to Head Gaskets, Bad Plugs, Bad Fuel pump, Bad DIS. Is there a cheap way to figure this out? Thanks all
