104,000 miles on it. Has duel personalities. Sometimes starts and drives smoothly without issue. Sometimes drives 10 miles, shut it off and restart and it stalls, is hard to restart and surges on the highway. At 55 mph it will lose 500 RPM'S. Will drop to 600 RPM'S tin will rattle, and engine will stall out at lights, and I'm not sure if I will be able to limp it home. I've replaced the air filter and NKG Platinum plugs and Beck Arnley coil packs. Engine codes read were 450 and 440, EVAP codes. Bought a new fuel pump but haven't installed it yet. Just bought CHEVRON/TECHRON injector cleaner. What else would you do?
What scan tool works best for import cars (Toyota Honda, Suzuki) and do they have free updates? I am looking at Innova 5610.
Thanks, Dennis-
Replace the fuel filter and then pressure test the fuel line. If there was still an issue, odds are it is shot and needs to be replaced.
Check fuel pressure during concern but sounds like the fuel pump is nearing its demise..
Hi all. Today my scan tool arrived. None of the codes that AutoZ... told me about appeared on the scan tool (Innova 5610). What did appear was: a P1140 code. That has to do with the timing of the intake valves. Nothing to do with the codes that the autozone store gave me about the Evap. codes.
From what I have read, it could be several things, even the ECU.... The onset of the problem this year occurred when driving in a downpour and hitting some standing water on a slightly flooded street. I am asking if the foam in the ECU box could have gotten wet and shorted something, or if there could be a short in a wire somewhere, or even if I just need an oil change. The timing solenoid appears to be a 3 wire plug on the passenger side of the car, otherwise the code would be P1145 instead of P1140.
If I try to pull these intake timing solenoids I am going to have to get new gaskets (a dealer only item?) Please tell me the steps you recommend I take to troubleshoot this problem. Would cleaning the solenoid be worthwhile? How likely is it that the ECU could be fried? Have you seen this problem often before? What is the most cost effective way to proceed? Thanks in advance to anyone that contributes to this solution. I am grateful to you for your expertise.
