Hi, I was reading some articles on the 95-99 4.3's with CPFI, is it true that all them have problems with fuel lines leaking and the intakes cracking? Just courious because I have a 99 GMC Jimmy with a 4.3 and I keep getting a misfire code on cylinder 4 and I cant find and problems, should I maybe lift off the upper cover and take a look?
Also is CPFI the type that looks like TBI after removing the air cleaner assembly?
Thanks
