Re: 1991 ZR1 ODB1 Port Location
In order of likelyhood the usual cast of characters that will cause a "Badly Tuned Chevette" syndrome are:
- Fuel injectors
- Coil packs
- spark plugs/wires
- Fuel pumps
If the fuel injectors are original, they are the most likely culprit.
Get one of the FBI (Fast Boys of Illinois) to pop over for a quick diagnosis, it will save you time, trouble and money.
