Hey guys, I have a '89 DL Wagon 2wd, 5spd SPFI. I recently replaced the timing belts after one broke, got 'er running again and she ran great for awhile and recently when driving up hills or takin it up to WOT, it cuts out and stumbles badly. I repalced a couple of cracked PCV hoses, put a new air cleaner in, plugs wires cap and rotor and a coil. I have cleaned the Air control valve and seems to be working properly. I also checked the coolant temp sender plug and it was fine and I also checked and made sure that the EGR valve is working. Any ideas on what is the cause of my troubles.
....Also my ECU is flashing code 21(coolant temp sensor or circuit) and code 34(EGR Solenoid or circuit)
Thanks for the help in advance, this site has been great for all kinds of info much better than the Hanyes book!!
