Checklist before a tune...
At one point in time, someone on here had a nifty maintenance checklist to do BEFORE you went to your tune.
I am tuning myself, but am almost out of answers and I am wondering if it isn't mechanical. I have utec and many mods and just when i get AFR's good and no knock - I'll get knock 2 days later in a completely diff. MLP and RPM than I had before. And sometimes it'll be 20-30 knocks!! Then I'll reduce timing or something and the knock is gone - until 2 or 3 days later. So, hence the checklist , I'd like to comb thru any possibilities of problem one by one. I have already: changed plugs, replaced front o2 sensor, leak test done professionally, compression test (fine) , oil change, cleaned MAF, cleaned filter, cleaned IACV thingy (replaced gasket too). Took it to Godspeed and had a decent tune (i think). Problems : rough idle, stalls out, bucking and hesitate past 6k at any TPS. Knocking. Thanks for any suggestions

Any ideas? I dropped the car off today to get a complete comb-thru. They're gonna check all hoses and pipes for leaks. They also mentioned my alternator could need attention, hence the stalling.

That was it! Thanks. And the fuel filter's not a bad idea either. |
