After getting my power steering pump replaced last month, I noticed a sight hesitation from the engine at about 1500 0 2000 rpms when the engine in under a slight load or slight incline with little or no acceleration. A little background, when I had the T-Bird towed in for the power steering pump, it was during a heavy rain storm. Right after picking up the bird from the garage after the pump replacement, I took it to the carwash to get dirt and grime off it. At that point within a few days, I started getting the hesitation. Driving down the highways at 55-70 mph it runs like a top. It’s just at the 1500-2000 and about 35-40 mph. There is no check engine light on.
The story thickens. I went to check the gas cap and the gas cap was loose, not fully “clicked” engaged. It was over the filler pipe but loose. So I ran a can of Seafoam thinking perhaps some water got in the tank. The tank was at ½ full so adding the 16 oz. can of Seafoam was perfect dilution for aggressive water removal of 2 oz.’s per gallon. I drove it till almost empty and it seemed to get better, I refilled the tank yesterday and added one can of k-100 to catch whatever water there may have still be in there, if there was any in the tank in the first place. I took the car out for a spin, and she ran flawlessly except for one very small stubble at the usual 1700 rpms @ 41 mph.
I know I should have a scan tool, which I will buy this week to check for codes. I thought, could it be fuel pump? I just had the fuel filter replaced about 4 months ago. Then I thought I would have more hesitations over the entire driving range. Same with a spark plug and COP issue. Then I thought perhaps the throttle position sensor or throttle body needs cleaning. With 21k miles on the clock, it could of got fouled when the power steering pump went and spewed out oil when the power steering pump bearing let go.
Any ideas? Oh and BTW I confess, I was the Bozzo who didn’t put the gas cap on tightly in the first place some 2-3 months ago after the previous fill-up. The gas cap light never came on either.

My head is hurting now.. Mine is second from the right or is it the far left one.. Darn, I can't remember my own bird..
