Yeah Yeah Yeah, another new memebr trying to resolve an issue.

CAR: 98 V70 AWD Turbo 150K

CEL: Codes: P0304, P0300, P0302 (random Misfire on 1, 2, 4, and random)

Car runs great (very strong)until about 4K and then begins to sputter. When it sputters, CEL flashes. Could it be bad gas, plugs, coil, vac leak?

Figured I'd ask before throwing tons of parts at it.

Thanks!!

 

I would start with a compete tune up including cap,rotor,wires, and plugs.

 

picked up cap, rotor, wires, and plugs. I cleared the codes and tested it before changing the parts. No misses at all fre-reving it. Parts go on tomorrow. How long of a drive cycle does this car have?

 

For everything to show ready it is a long complicated process.
Somewhere on here the drive cycle is posted.
