Help with knock

Tuesday, March 18, 2008 7:06 PM

This may sound dumb, but how do you know if your engine is knocking with the VCM scanner, which readout do i look at, the KR? Also, which injectors do you guys use in our cars more, the peak&hold, or the saturated ones? Thanks for any info, and Sorry if these questions are kind of dumb.

Allright, I tried to find some RC injectors around 550 cc, but they don't make them in a peak & hold. Can I run saturated in my car, or do I need peak&hold? If I do need peak&hold, can some one tell me some other types of injectors I can run, and what you guys are running? I would like some 550cc-650cc injectors. Thanks.

Your vehicle runs High Impedance injectors (11-14 ohm range for your year/make/model), which are also termed "Saturated" injectors, not "Peak And Hold" ("Peak And Hold" is synonymous with Low Impedance injectors, as found on the 98-00 2.2L, and 95-98 2.3L/2.4L). RC does in fact make a 550cc in the High-Impedance/Saturated category, as well as in Low-Impedance/Peak And Hold.
