2001 3.4 2WD bought w/no working gauges, CEL w/ knock sensor and 0171 drove truck home in limp mode! Replaced both sensors w/denso also did intake gaskets and new injectors next code TPS replaced titans with eBay part.///still in limp and now throwing VSS. Of course that was new abs all 4 abs/trc/vsc module replaced with ebay part lol. Still no gauges still VSS code of coursed VSS The one on trans that I can’t even for sure after reading couple hundred threads know if it’s eve in loop. So bought 3rd ECM and VSS code gone but still in limp mode and still to lean. Should have good air flow clean MAF and w/DIY test fuel pump ok so leak could clear code but still in limp mode How is too lean and Limp mode connected. Is there diagnostics tool that can clear code. On current diagnosis tool incomplete cats and evaporated still red. I cannot get through any drive cycle too lean code pops and it chugs even worse than hitting 3k rpm in limp please point me in direction
