Wouldn't the vaccum hoses cause this problem upon startup? they look ok to me, no cracks or tears.... yesterday I* took out the fuel pump fuse after the problem happened for about five mins then put it back in..... same shit... with the MAF unplugged it runs like complete shit...so i dont think its the maf.. how would i check if it is the coolent temp sensor? How long does the battery have to be disconnected for it to reset the ecu?
