Default Lt1 Troubleshooted Out Need Help

I Have A 96 Coupe That Has Had An Intermittent Hesitation Or Bog At Slow Speeds For 6 Months Now. I Have Rebuilt Or Replaced The Following: Spark Plugs, Wires, Fuel Filter, Fuel Pump, Maf Sensor, And Opti-spark To No Avail. My Problem Has Gotten Progressively Worse And Now It Just Dies From Time To Time While Running. After Sitting For 15 Minutes Or So It Fires Back Up. Seems Like The Condition Is Exacerbated Under Extreme Heat Conditions. I Ran The Codes Again Yesterday And It Came Back With A Maf Code So I Swapped It Out Thinking I Had My Problem Fixed.

Did you trouble shoot the code to determine that the MAF was bad? Or did you just throw more money at it by shooting the messenger, because the code came from the MAF? It sounds more like it's time to START troubleshooting.

RACE ON!!!

Could it be a bad Throttle Position sensor? That would stall out your car and seems to get worse when the car gets hot.

Good luck

You need to stop spending money on parts and get the Helm Factory Service manual for your year.

www.helminc.com

Then start troubleshooting for real, cause right now, all you're doing is waisting money and time.
