1991 SPFI manual Loyale w/212k miles
So I am waiting for a pressure gauge to come to test the vacuum, I am still driving it to try to diagnose.
It never really has full power but I noticed in different gears on flat ground I get to certain RPM/speeds.
1st gear 5k+RPMs 20 mph
2nd gear 4k RPMs 30 mph
3rd gear 3k RPMs 40ish mph
When it hits the max RPMs, the gas cuts even if I floor it and only will come back on once I take the gas off and let it go below the RPMs listed and then it will get gas and cut out again relatively consistently with the numbers I posted above. It never has the power I know that it should in any gear and the RPMs never match the power I expect like what I had when it was functioning properly.
Does this still sound like resricted exhaust?
I will check pressure and or pull O2 sensor to see if I get the same results next weekend.
