It starts perfectly fine when it’s hot out!


How’s your exhaust is it blowing black smoke (dumping fuel)I get around 14.5 to 15 highway before I did new injectors just finished Thursday hope to get better numbers on this tank of fuel

How much of your exhaust is missing your other post has exhaust codes maybe fix that first? Exhaust builds up back pressure necessary for valves to stay alive

you definitely need the correct exhaust velocity. i must have totally missed your post with the obd 2 codes. where are you on those. intake leak could cause some of those other codes potentially but again i think you would notice other symptoms aswell. you could check for intake gasket leaks by spraying carb cleaner or starting fluid around the edges of the intake. if there is an immediate change in rpms in a certain spot when your spraying it thats your leak.

Dumb question, but where would my intake be? Or what does it look like?

its the thing that sits under the thing that your air filter intake tubing is attached to lol. the intake manifold top of the engine its the whole thing that sits between the valve covers.

your looking at about 1400 for just the block and heads you would need to transfer everything else from your engine. not to mention its still not something i would suggest for a novice without someone there to help.

Here’s the upper intake ( black plastic) lower intake
( aluminum) out and reassembled this is a big job to take on for some even though others say maintenance it’s buried under a lot of sh#t ask a friend to possibly point you in the right direction google or YouTube has videos on checking for leaks

couldn't ask for better pictures to know what your looking for. and it is definitely a big job and a bunch of ways to make it worse than it already is.
