Keeping LKQ in business
Ok so I'm still working out the kinks on my 1995 2 door Hoe. Now, I should have done some more research before I bought her but she had everything I wanted (Barn doors, 4wd, 2dr, etc). We put a new crate 5.7L motor in her. Kept the existing intake, TBI and all the accessories. Since I got her back together, I've noticed a tick/hesitation in idling at a stop light and she bogs down when I accelerate but cruises great. I've replaced the o-rings at the delivery and return lines in the back of the TBI with AC-Delco ones. I've replaced and changed the harness for the engine coolant temp sensor. I've replaced the harness for the engine coolant temp sensor (the one that goes into the left side of the block). There was a small vacuum leak off of the TBI, we fixed that. I replaced my ground strap from the block to the frame rail on the right side. Timing was set at TDC and hasn't changed. I replaced my t-stat with a 195 degree one. I also replaced my vehicle speed sensor on the tranny as the tranny wasn't shifting right.
Onto what it does. When I crank her up in the morning, she idles at 1k at first until she settles down and then it's 550-600 once I hit reverse and pull out. Heading down the road, she's a bit sluggish but once I'm about a mile into my 6 mile journey to work, she's steady. If I stop at a stop light, the tach will bounce from 500 all the way up to 1k and sometimes the tach bounces and there is no corresponding engine response. She used to lurch a bit when the tach starts bouncing but she doesn't do that since I replaced the o-rings and ECT sensor. She smells like it is a little rich. I just can't figure out how to get that idle smoothed out and I've run out of my shade tree/internet search ideas. I'm thinking my fuel pump may be going as my gas gauge bounces a lot and right now, after a full tank, I'm like 1/4 of a tank over full. To test the fuel pressure, I'd have to rent the tool from O'Reilly's because my system has no Schrader valve, I'd have to rig one in before the fuel pump.
Any suggestions? Any help is appreciated. It may also just be that the TBI is a piece of junk as my husband keeps telling me and he's going to get his wish to get a new intake and carb.
