Re: Exhaust changes causes problems
Roger,
Its possible that the less restrictive exhaust may have caused the AFR to lean out somewhat. Can you get a scantool on it? The 4500rpm region is where you might expect Knock Retard to come in and the hesitation could be the ECM pulling timing out. Just possibilities which need to be verified by a scan. |
