I have been battling this problem with my CSVT that I recently purchased for almost a month now. I bought the car knowing it had issues and I honestly thought it would be an easy fix and I would be on my way with a cheap fun car for almost no money invested. Boy was I wrong, this thing kicked my ass!
First thing I figured seeing that both banks were lean was that I had a bad fuel pump, clogged filter, or bad regulator. I drove the car around for a few days with a fuel pressure gauge sticking out of the hood and I had solid fuel pressure all the time. The car was intermittently bucking and real doggish and even while that was happening my fuel pressure always remained solid. Just for ••••s I replaced the filter. No dice.
Next thing I figured would be the infamous intake gaskets. With the help of this forum I learned that these cars were prone to gasket failure causing vacuum leaks almost impossible to trace. $40 and a few hours later my car is still a gutless sputtering POS!
At this point im getting pissed. I physically removed every single vacuum line and inspected them for hidden cracks or something and came up with nothing. I also went to the extent of removing every plug wire and spark plug and fully inspecting them thinking maybe I had multiple issues on my hands. Still no luck. Against everything I believe in, I start to throw parts at it. I bought a fuel pump thinking maybe it wasn't putting out the volume it needed but had just enough pressure to check out ok. That was a waste of $100.
In my head I know there is something going on between the MAF and the O2s that is affecting the entire engine (not just one bank) that is causing a lean condition. The last thing I could think of was to try another MAF. Sure as ••••, I cleared the codes with my scanner, disconnected the battery and threw a junkyard MAF on it and as soon as I laid my foot on the throttle I knew I had fixed the problem.
This car is a beast! Never in a million years did I think 200HP could feel this fast. I am amazed at how quick this car is and how well it runs! Ive owned countless foxbody 5.0s and I would go as far to say that this thing would give a stock mustang a run for its money. I don't know if I have ever driven a front wheel drive car that could literally boil tire powershifting third gear. And to feel the secondaries come on is comparable to that of a boosted car. So fun! :laugh:
I rarely post on any forums, just mainly lurk and take in all the info. Being that this site is packed full of good info and a group of people so dedicated to a car that is less than desirable, I felt the obligation to say thank you. I hope my experience can help others with a problem that seems all too common and often goes unsolved. THANKS CONTOUR.ORG!
