PRESSURE PLATE ISSUE...

YOU NEED TO SWAP NEW CLUTCH HAPPYMEAL (CLUTCH, PLATE, THRUST BEARING ETC)
CHECK FOR A VACUUM LEAK..... (if i idle in first with the clutch down it revs up and down and almost stalls out)

OR YOU MIGHT WANNA START BY CHECKING YOUR HYDRAULICS.. MASTER & SLAVE CYLINDERS (about 30.00 to rebuild) - its the cheapest answer....

OTHER THAN THAT YOU NEED TO TAKE TRANNY DOWN AND LOOK AROUND....

AND LAST BUT NOT LEAST - I WOULD GET THAT BATTERY CHECKED..... MOST ADVANCE AUTO PARTS WILL DO IT FOR FREE......
