car can barely accelerate, blinking CEL
ok guys so im having major engine problems and i would really appreciate any help as im really scared.
car has 152k on it. the check engine came on about 10 months ago and i got the codes read, came out to be a front o2 sensor and some weird one that had to do with a vacuum leak (p0505 and p0300 i think, ill get the exact codes when i get home). i didnt think anything of it until about a week ago i noticed the start to bounce back and forth on acceleration only at low rpm and particularly in higher gears. Now the problem has gotten way worse and i can barely accelerate, literally, and the cel now flashes when i try to accelerate and the problem happens. it feels like the clutch is slipping almost when i try to accelerate but ive tested that and the clutch seems to be fine. ehen i got the codes read about a week ago it showed no signs of misfire but it has gotten much worse since then. ive also heard a loud, sharp pop or crack when accelerating at two different times, almost so sharp i didnt think it was exhaust one time, it sounded like a crack but the second time was deff exhaust.
i barely have any tools when i live so im gona drive home this weekend to check it all out. i wamt ti clean out the tb really good, the maf, fix the 02, but what else should i check, like the valves, compression, coils all that stuff. if anyone has any input on what this could be coming from that woyld be amazing. thank you in advance
