Engine seems to miss while cruising...

[BlackFox5.0]

I fixed my last problem which was the fuel pump hose popping off at the pump, but now While driving, the engine seems to miss, and I literally get thrown forward (not very hard but noticeable)

I have a new fuel pump, sock and filter, 36# injectors, 80mm Pro-M, timing at 11-12*.

I don't know what else to look for and what could be causing it....

 

[jaymac]

could be as simple as the ignition wires cross-firing...happened to me... Make sure they're not crossing/ touching each other. also, did you replace the fuel filter and plugs/cap/rotor too?

Most likely thing is igniton componets like jamymac said, but a bad TPS will cause similar symptoms as well. Best bet is to see if it throws any codes.

Dump the codes and see what the computer says is wrong…

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.

Cap/rotor is new, just changed fuel filter a few days ago.

Pulled codes and just got non-functioning EGR, which I know about, and is not hooked up

Would a clogged (dirty) injector cause this maybe?
