just got back from nopi in atlanta and my car ran like crap the whole way there. so i have some questions. i get the worst gas mileage on the street maybe 15mpg, but on the highway maybe like 25mpg. everytime i touch the gas a huge cloud of smoke about suffocates the person behind me and my back bumper is covered in sut. i burn oil like you wouldnt believe. i changed the valve seals not too long ago but that didnt fix it. the kid who had the car before me bored it out and i think that may be the oil problem but im not sure. if anyone knows whats goin on please help. motor is a 95 gsr with 81.5 high compression pistons, aem fuel rail and fpr at 40lbs idle. walbro 255 fuel pump, and 355 injectors

 

do compression and leakdown tests. sounds like it's running really rich too.

 

checked compression 11.5 across the board. fixed fuel pressure turns out it's supposed to be 40lbs full throttle, need to get a new distributor i think, thanks for your help

 

You obviously didn't check your compression because 11.5 is not a valid compression result. You are looking for a psi number.

 

no the guy checked it and said that the psi was equal to 11.5

 

do it yourself. not that hard. you're looking for the psi number for each individual cylinder.

 

If it were 11.5 psi in any cylinder, it wouldn't be running. You are looking for 250+ psi per cylinder if your compression ratio is 11.5:1.

 

Agreed. Who did your Compression Test?

 

the guy checked it because i dont have a gauge. he said the compression was good 11.5:1
