Hi tech Posted August 28, 2017 Share Posted August 28, 2017 Hi everyone So my problem is a random misfire. The timing chain and head were replaced at 140,000 miles it now has 141,000 on it and i have replaced the map and iac because those codes popped up after changing the timing chain and head. After changing the iac now i am getting a random misfire code on 1 and 2 cylinders and some times 3 or 4 and the coolant temp is well above 240 degrees. my question is what is wrong and how do i fix it. Mind you I have changed the coils out on it too. It has the 2.4l dhc engine. Quote Link to comment Share on other sites More sharing options...
HONDA CRX 88 SI Posted September 7, 2017 Share Posted September 7, 2017 Well if your problem started with the timing chain been replace I would check for proper base timing and check the head gasket could of been compromised Quote Link to comment Share on other sites More sharing options...
Hondak20a2 Posted November 12, 2017 Share Posted November 12, 2017 So you weren’t getting those codes before the timing chain install ? Quote Link to comment Share on other sites More sharing options...
