Can't get my new engine running correctly

shurb125 · January 21st, 2008, 06:23 PM

My cay just won't run correctly, the idle surges, throttle response is terrible, then it wouldn't start and I pulled plugs and they were wet with gas and bought new ones and it cranked again. With all the new and modified parts and peices do you think I need to get a chip burned for the mean time untill I can get a piggy back system? I built a 306 with the following parts: I have TFS trackheat upper and lower intake, BBK 70mm throttle body and egr spacer, 24# injectors, stock fuel rail, Accufab AFPR, 80mm MAF calibrated for 24's, TFS heads 58cc ported and polished, 1.6 TFS roller rockers and pushrods, TFS roller lifters, Anderson HiRev valve springs, TFS stage 2 cam, TFS double roller timing set, DSS Pro pistons -13cc, stock rods and crank, BBK L/T headers with BBK O/R H pipe and BBK underdrive pullies. I have removed the A/C and the charcoal canister. I have also moved the P/S to A/C location. Any help or suggestions are welcome!

Checked all vaccum lines all is good, I just beleive that there is more to it than that, it seems no matter what you try it still dosen't run right.

what year is the engine? do you have speed density or maf?

SALIV8 · January 21st, 2008, 09:38 PM

try clocking your maf

dr.gonzo! · January 21st, 2008, 09:47 PM

SALIV8 · January 21st, 2008, 11:10 PM

shurb- thats correct, 90* more or less, see if that helps.

sounds like timming way out.

e3sean · March 1st, 2008, 09:56 AM

did u get it figured out? u can check and see if u have a leak spray some carb cleaner around the intake gaskets if the motor reacts in any way u have a leak..

ujslost · March 1st, 2008, 10:06 AM

Sounds like timing is way out or some plug wires are crossed.
I just ran into this same problem on my carbed engine. fucker would crank and pop thru the exhaust and the carb. It turned out my #3 and #7 wires were crossed. Found out after replacing dist, plugs, wires, intake gaskets. Always go back and check what you did, and double check the basic things like firing order. PPL get so comfortable with these areas they easily overlook the little things like I did.

Come to find out I had the wrong MAF on the car, I bought one off ebay for 87-93 and it turned out to be one for a 94-95. Changed it to a C&L and problem solved

Now sue the hell out of those Ebay guys who tried to pull a fast one on ya. Or go to them and do a burnout all the way around there shop
