I have a 1990 honda civic that randomly stalls. The engine shudders, makes a popping noise if my rpms go too high, and I have no idea what the problem is.

I'm having about the same problem as you brother. My 91 hatch base has a dpfi d15. Has a high power msd ign system, header back exhaust with no cat (i bought it that way), and a cool air intake. If i try to run up over 3400 rpm it stalls out like i let off the gas and at about 3000 rpm i can give it gass again. Replaced the fuel filter and pump and still, same thing. Injectors, dizzy, pump and filter are good. SO WTF IS WRONG. I havent checked the TPS but have been told I have to take it in to get checked? ECU is throwing out 8 and 16, but dont think its right. Any help is greatly appriciated.

Test the igniter unit inside the distributor. Any CEL codes?

This seems like a logical place to start.

Will the first thing to do is make sure that the timing is set right. Then go from there may want to look into the codes that you r getting. They just don't show up for no reason.

Checked timing, its good. Checked Msd high power dizzy and blaster pack, theyre good. checked cas, its good. main relay is good and ive got plenty of fuel pressure. still stumped. any more thoughts?

I keep getting told it could be the tps. if that is the case i might just do a mpfi and d16 swap. but to just get it to run right would be great.

I was having a similar problem, except mine would sputter and run like crap at low rpm, and then when I got on it and brought it up to speed it would be ok. My fix was a zc swap. Haven't had this much fun in the car yet.
