ok. So my car has been acting up. Was throwing a check engine light. And it was a code 16... Read up people said to replace the main relay. The guy i bought the car off had a extra one he hasnt put in. so i did it. Drove it around a bit and when my check engine light comes on it wouldnt let me rev passed 4 grand. Well... Went to the store today to get cigarettes and a drink. Took off normal and slow and the car started bucking bad in 1st and second. 3rd gear at low rpm was fine. Took it home and parked it. Had some spare time so i tried starting it again. Would rev and when i give it gas it would sputter and wouldnt climb rpm's. Then it dies. Any Ideas guys? its my daily so i got to get the thing back on the road..

 

Bump. Any help would be great guys

 

Update: i can smell and see the fuel. So its getting fuel. Checked my plugs and i have oil in them. Could that be the problem?
