Bought my 03 260K mile yeller feller cheap but needing a lot of love. Swapped out the the tired and noisy engine for a sweet JDM version and keep pecking away at its re needs .Almost there. Problem currently with low speed performance when hot - sluggish take off, but crruises easily at 65-70. Runs good cold. No change with 02 sensor swap.MAF? Where is the MAF on this car? Welcome suggestions!.
