Blazer stalling :(
#32
so i replaced the fuel pump and the truck ran really good for like three days now it stalls in drive after a while of driving but if i put it in neutral the truck doesnt stall. when put in drive it jumps like if it was a stick with the clutch let go. i did get two codes p1870 and a p1509 which is the iac and slippage in trany hard shift 1-2 gear. im dreading a tranny rebuild..... hope its not the torque converter

Don't fear the P1870. That code popped up on my '98 Jimmy. I installed the TeckPak FitzAll replacement TCC valve and it took the problem away. Here's a link to the valve:
TCC VALVE from Teckpak / Fitzall
There are several write-ups about how to install the valve. I was able to install it myself pretty easily in one evening. I would also suggest installing a Trans-Go orange box shift kit while you have the valve body off the transmission. It will improve the shifts and extend the life of your transmission.

so i got the blazer back and running it turned out that the fuel pump was fried thank you all for the help much appriceated. i also did a complete tranny rebuild because my torque converter was begining to lock up which was causing my truck to idle rough at a stop light and sometimes would stall the truck. thank you all once again
