Subject: Re: 90 C4 performance degrades the longer it runs by Matatk on 2011/11/10 12:30:23 Did you pull the battery cable and turn on the headlight switch? That removes any residual power. You have to reset the ECM for your fuel tables since the old injectors probably made it all out of spec trying to adjust. Also, have you replaced the O2 sensor? One wire sensors are a maintenance issue...they should be replaced at like 30-40,000 miles. That will also make a difference with how it runs. Go to rockauto.com, they have the best prices. Get a Denso/NGK sensor. Matthew |
