Time to ask the experts.
I have a 2003 SES OHC "U" with 200k miles that my daughter drives. It recently began to 'miss' during acceleration. No noticable issues at idle. Progressively got worse to the point of no power. Tried to drive it home from her school and didn't get very far before the DPFE
hoses blew off. After that happened, it had a bit more power, but still 20 mph max. Gave up and towed it the rest of the way home.
After doing some basic 'garage work' investigation (vacuum leaks, MAF
cleaning, etc.) decided it was bad cats due to no exahaust at the muffler.
The only code that had showed to this point was P0171 (Lean bank 1)
Just had the entire exhaust replaced; 3 new cats, pipe, and muffler $900
The exhaust guy told me that they all fell apart and the rear pipe was totally clogged. He also told me that there was a miss somewhere that he noticed during his test drive.
I got it home this week and attemped to address the miss.
I just changed plugs and wires, and a replaced the DPFE
(melted)....took it for a test drive.
1 mile down the road, the DPFE
hose blew off and I limped home at 10-15 mph. Exact same issue from the beginning.
No codes were set during this 20 minute drive.
I'm not a certified mechanic by any means, but I thought I knew a little something. This one has me baffled. I cannot locate any person with exactly the same issues in the forum; hence new thread.
Any help would be greatly appreciated. At this point, I feel like I've thrown $1500 at it for no good reason.
Hopefully I've include all necessary info; I will clarify anything else if needed. Thanks in advance.
