Ok i know this is not on my camaro but can help anyone with a MPI engine with my problems, plus the people on the ranger forums are ...... well not to helpfull


anyway i got the 2.3 I4 and EVERY sensor is new, new distb, coil, plugs, wires, filters, compression is great and it hold 21in of vaccum at idle, no cat, anyway it got all i get is 13-15MPG's and it has no power, i mean i know its a lil 4 banger, but a few months ago i could hit 90 with it by itself and 80 with my trailer behind, now i am LUCKY to hit 60 with my trailer behind, and it wants to run HOT too, got a rad flush, flex fan, and 180 stat ....... fuel pressure is 29-34 running but putting it into "test" mode its like 36PSI and thats within the 30-40 range the book says for the "test" mode

my thoughts ......... bad/cloged/dirty/cruddy injectors

please help, lol i love this thing as a D.D. dont have to worry about knicks and dings and all

btw its an 88 ford ranger, with 160k, engine was taken real good care of its spotless under the valve covers

 

You have 240cc bosch injectors, pintle type. might not be a bad idea to have them cleaned, should cost no more than 60 or 70 bucks for all 4 anywhere....

 

i can pick up a set of cleaned and rebuilt for that price and they also offer to buy back the old ones

thats all i can figure can be wrong with the lil truck, hope to get a little more feed back, im sure someone has been in this situation with their TPI or V6
