DTC codes

[killj0y]

Been getting codes p1443 and p0401. I want to troubleshoot around the egr valve since I've tried to replace it but that sob isn't coming off! Anyways I regularly clean the maf, iac valve (or is it icv), and throttle body.

Any tips where to start or should I just replace a part or two and go from there?

Bump...no advice?

My advice is to Search.

P0401 is common and typically is the DPFE, its special silicone hoses, or a clogged EGR port. The EGR valve itself is rarely the problem.

P1443 is also common, Evaporative Emissions fault. It has to do with the cannister by your spare tire and the fuel tank. It could be a bad Cannister Purge assembly, gas cap, filler hose, etc. Even a simple google search of P1443 will tell you a lot.

I do search but I get a lot of conflicting information so I thought I might narrow it down based on symptoms.

Ok so recently with those codes after the engine and emissions warms up the truck feels like it misses at speed and at take off with the occasional back fire unless I rev it a bit high before take off.
