1996 Toyota Corolla Q&A
1996 Toyota Corolla Question: 1 leaky fuel injector replace bad one only or all 4 ???
car has 222,000 miles on it now all injectors were replaced about 11 years ago car had about 108,000 miles on it at the time had fuel injection system cleaned approx 2 years ago car run great but misfires occasionally with no check engine lite or codes im figuring most likely cause of misfire is leaky injector had complete tune up done last year also replaced fuel filter. fuel pump was replaced about 2 years ago - eddiec954
The best approach would be to replace them all with a set of matched injectors. - cardocIII
Have a mechanic find the source of the misfire first. - pushrod
