If they are clogged, check the overflow hose. If it is cracked this will let in lots of dirt which will clog the filter. This is a VERY common problem which MUST be fixed or it will ruin lots of stuff. > My question regarding the injectors, can I get a discription of how the > injectors fire?

Also, if this is the > case (firing irradiacally), would this be a bad ECU or wiring or ground? They fire in pairs, 1 & 4, 2 & 3. Erratic firing is most likely caused by loose connectors, which can be fixed rather easily and cheaply, but it has to be done carefully to avoid damaging them. If the spray pattern is poor, this is most likely due to water or dirt which has gotten in the gas. Bad grounds are not likely a problem after '69. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
