i have a 99 GT auto vert with about 125k miles. i bought the car in december of last year for dirt cheap (thing was leaking coolant bad, among other things). since then it's pretty much been a continuous project as it is my daily driver. I've been able to tackle most issues with it, but now i'm stuck.
The engine began running really rough recently. I parked it and went to work for about five hours and when i got back in the car it was driving like . I took to the forums, got the engine light read, and went to work throwing parts at it. the engine runs alright once RPMs are steady. however, accelerating is terrible. the engine stutters and just feels like it isn't getting any power. if i give it some gas, it'll run real bogged down like this for a bit and i can feel it kick and go back to normal at maybe 3k RPMs? like it decides to run normally for the rest of that gear. My gas mileage is also e.
My engine began to steam one night i discovered the coolant hose on the left side of the engine had come apart in the middle, the connected had dry rotted and the tube was dumping coolant into the compartment. i fixed this issue by just connecting the one half of the coolant hose to where it lead to instead of a second tube. just figured this was worth mentioning.
also a couple months ago i had 4.10 gears installed, my speedo is off by 10 mph. i recently replaced two o2 sensors, the fuel filter, and the evap purge valve. the engine only misbehaves really under load, with a small dip every once in a while in park. i put the car on blocks and put it in drive and unplugged each coil connector one by one and every single one had an affect on the engine, even tho the engine was running like hell with all the coils in.
the misfire throws no code because it happens intermittently, and the engine light will flash if i accelerate too much. the car has no issue reaching high speeds, i can easily hold it going 65 without issue.
i don't know what else to do. anything helps at this point. i just want the sport back in my sportscar.
